Claressa Shields had to choose which of her WBO titles to hold on to – and she has opted to vacate her light heavyweight title while holding on to her heavyweight belt.
That news was announced by WBO President Gustavo Olivieri.
“Per our rules, no WBO champion may hold titles in two different weight divisions simultaneously,” Olivieri posted on social media.
Shields won the vacant WBO heavyweight title – and a couple of other vacant belts to become the undisputed heavyweight champion – on February 2 with her unanimous decision over Danielle Perkins. The 29-year-old native of Flint, Michigan, moved to 16-0 (3 KOs), and added to a career that has also included becoming undisputed twice at middleweight and once at junior middleweight, plus winning titles at 168lbs and 175lbs.
Shields won the WBO’s vacant light heavyweight title – alongside the WBC’s heavyweight title, which confusingly is for women above 168lbs – with her July 2024 win over Vanessa Lepage-Joanisse.
Michigan’s athletic commission says Shields tested positive for marijuana after the Perkins fight. Shields says she has never used marijuana – which is not a performance-enhancing drug – and suggested her positive test may have come from secondhand smoke in the arena or contact with other people on fight night. She has appealed her suspension, and the head of the Association of Boxing Commissions has criticized the Michigan commission.
Claressa Shields Addresses Boxing Suspension Following Positive Marijuana Test
Claressa Shields has been having a tough time following her boxing suspension for testing positive for marijuana.
The 29-year-old appeared on Tamron Hall to explain how her oral mouth swab could have come back positive after her match in Michigan.
“One, the place reeked of marijuana,” Shields explained, describing the venue where the boxing match occurred. “Before I got to do the mouth swab, everybody was hugging and kissing me in Flint. … I know some boxers don’t stop and greet the fans but I’m not one of them. I hugged and kissed everybody back.”
Claressa Shields says she’s never used weed. Did secondhand smoke cause failed drug test?
The saga of boxer Claressa Shields is unfolding.
She is a two-time Olympic gold medalist. A three-time undisputed world champion. But, at 29, the self-proclaimed “GWOAT” (Greatest Woman Of All-Time) is facing a question involving her integrity.
Could Shields have tested positive for marijuana even if she never used the drug?
According to Shields, that’s what happened after her last boxing match, a victory over Danielle Perkins Feb. 2 at Dort Financial Center in her hometown of Flint, Michigan. The drug test results have not been publicly released, but Shields has said a saliva test detected “trace” amounts of marijuana, a prohibited substance in competition for professional fighters in Michigan.
Ten days after dominating Perkins in a fight that improved Shields’ record to 16-0 and elevated her to undisputed heavyweight champion came the gut punch. She was suspended by the Michigan Unarmed Combat Commission (MUCC), which regulates boxing in the state, and such discipline generally is upheld by other states.
But she’ll soon get a chance to contest the decision.
On March 6, during a pre-hearing meeting before an assistant attorney general, Shields will request her suspension be revoked, according to her lawyer, David Slutsker. “We will present evidence … and be open to any questioning they have,” Slutsker told USA TODAY Sports. Depending on the outcome, a formal hearing could follow.
For now, Shields faces a 90-day suspension, a possible fine and newly surfaced claims about her possible exposure to the drug.
Other boxers tested positive
Shields was not the only boxer on the Feb. 2 card to test positive for marijuana. Eight of the 16 boxers on that night’s card were drug tested by swab, and three tested positive for marijuana, according to Dmitry Salita, the promoter of the show, and Shields’ attorney, Slutsker.
“That number is highly unusual for a single boxing event, particularly one featuring Claressa and other elite athletes,” Salita said. “Given the circumstances, it’s important to review the testing protocols to ensure consistency and fairness.”
Joe Hicks, a middleweight from Michigan, confirmed to USA TODAY Sports that he tested positive for marijuana. Salita said the other boxer who tested positive for marijuana was Skylar Lacy, a heavyweight from Indiana, who did not respond to USA TODAY Sports’ requests for comment left by voicemail, text message and social media.
Hicks, who is 12-0 as a pro boxer, said he worried about potential consequences because he works for an insurance company where “you can lose your job for taking any drugs without a prescription.
“When they called, I was, like, wow,” he said of learning of the results. “I don’t take drugs.”
Adding he was also surprised to hear Shields tested positive, Hicks speculated that marijuana smoke inside the Dort Financial Center in Flint triggered the positive tests.
“Oh man, it was everywhere,” he said. “I’m not exaggerating. … I was getting dressed to take pictures with my family; it was like a big cloud of weed. When you go in the bathroom, it’s just a big cloud of smoke that hits you. You smell nothing but marijuana.”
Marijuana is legal in Michigan but banned at Dort Financial Center. However, Salita and Shields’ manager, Mark Taffet, said the smell was noticeable.
“The hallways smelled horrible,” Taffet said. “… Like where (Shields) took the post-fight (drug) test, that sort of ring of hallway around the building, that smelled terrible.”
Jeremy Torrey, general manager of the Dort Financial Center, declined to comment to USA TODAY Sports.
Secondhand smoke a risk?
Whether secondhand smoke can cause a non-smoker to test positive for THC, the active ingredient in marijuana that produces a psychoactive effect, depends on the exposure conditions, according to a 2015 study published in Journal of Analytical Toxicology.
The study, which focused on “extreme cannabis smoke exposure conditions tolerable to drug-free nonsmokers,” reported, “Positive tests for THC in oral fluid and blood were obtained for nonsmokers up to (three hours) following exposure.”
But the study also concluded, “positive tests are likely to be rare, limited to the hours immediately post-exposure, and occur only under environmental circumstances where exposure is obvious.”
A 2004 study published in the Journal of Analytical Toxicology reported, “Passive exposure to cannabis smoke in an unventilated room has been shown to produce a transient appearance of THC in oral fluid for up to 30 (minutes). However, it is well known that such factors as room size and extent of smoke exposure can affect results.”
Salita, the promoter, said, “The amount detected was negligible and consistent with potential secondhand exposure rather than personal use.”
Shields had said the saliva test showed “trace” levels of marijuana in her system, but she has not publicly released the test results.
What Shields may challenge
Victor Conte, who describes himself as a “dietary supplement and training adviser” for Shields, said the boxer told him she had concerns about how her saliva test was administered after her fight Feb. 2.
Three-division undisputed champion Claressa Shields has received some good news in her ongoing battle to disprove a positive test for marijuana.
In an email sent to Dmitriy Salita, Shields’ promoter, the WBO founding president Luis Batista Salas agreed to grant Shields a stay of proceedings, which will allow her team time to make its case with the Michigan Unarmed Combat Commission and in the meantime avoid a penalty from the WBO – including the possibility of Shields being stripped of its title.
Shields won a unanimous decision over Danielle Perkins in her hometown of Flint, Michigan, on February 2, capturing the women’s heavyweight undisputed championship. But she was later suspended by the Michigan commission after her post-fight drugs test came up positive for marijuana. The WBO subsequently issued a “show cause notice” that gave Shields 30 days to clear her case.
Thursday’s WBO communication to Salita was an acknowledgment that Shields is waiting on a meeting date with the Michigan commission to seek a revocation of her suspension and an agreement on the part of the sanctioning body to pause any judgments against Shields in the interim.
“Having considered the arguments raised by Team Shields, this Committee hereby grants the request for a stay of proceedings,” wrote Salas.
The WBO’s decision comes on the heels of Monday’s public statements from Michael Mazzulli, the head of the Association of Boxing Commissions, who told BoxingScene that the Michigan commission’s actions were “overkill” and advised against stripping Shields of her belt.
“You can blame a system that’s broken within the state of Michigan,” Mazzulli told BoxingScene.
Shields, 29, is suspended from fighting only in Michigan, but she is seeking full exoneration. She maintains that she has never used marijuana, and on Thursday she appeared on the “Tamron Hall Show” to discuss her case.
“The place reeked of marijuana,” Shields said of the Dort Financial Center after her win over Perkins. “And then, before I got to do the mouth swab, everybody was hugging and kissing me in Flint. Everybody there, my cousins, sister, brother, friends – everybody was hugging and kissing me. And I know some boxers don’t stop and greet the fans, but I’m not one of them. I hugged and kissed everybody back.”
Hall essentially made Shields’ case for her, citing a study published in the Journal of Analytical Toxicology that asserts inhaling second-hand marijuana smoke can lead to false positives in testing. Shields says she also submitted to a urine test that came back negative for marijuana.
“I guess I’m just guilty and I don’t get to prove my innocence,” Shields said. “I’m just already guilty.”
Cris Cyborg is set to make her return to the boxing ring on March 3, 2025, when she challenges Karen Fernandes (not Claressa Shields) in a four-round bout in Medellin, Colombia, in the Super Middleweight division (154 pounds).
The former Ultimate Fighting Championship (UFC) and Bellator MMA Featherweight titleholder is 4-0 as a professional boxer, a career that began in Sept. 2022, earning two unanimous decision wins to go along with pair of knockout victories.
Cyborg has been balancing both her boxing and mixed martial arts (MMA) career pretty well, with her last fight in the ring coming in June 2024. Four months later, she won the inaugural PFL Super Fights Women’s Featherweight Championship by defeating Larissa Pacheco via unanimous decision in a hard-fought battle in Riyadh, Saudi Arabia, improving her win streak to eight straight.
For now, the fearsome striker does not have another PFL fight lined up (or any other MMA bout) at the moment, but at least she has the freedom and luxury to be able to partake in boxing bouts on the side to keep her skills sharp and schedule busy.
After undisputed world champion boxer Claressa Shields was suspended from competing in Michigan for testing positive for marijuana, her promoter Dmitriy Salita says he’s confident she will be cleared of wrongdoing once the investigation concludes.
A statement from Dmitriy Salita:
“Claressa Shields has built her career on hard work, discipline, and an unwavering commitment to clean competition. She stands by her record, her historic achievements, and her integrity as a world champion. She has been an inspiration to countless men and women throughout the United States and throughout the world since she was a teenage Olympian.
This is a pending matter with the Michigan commission and, as such, I cannot share much more. However, we are 100-pecent confident that Claressa Shields will be vindicated when this matter concludes, and all the evidence is heard. One thing I can say with confidence, Claressa Shields did not and does not ingest illicit drugs of any kind including marijuana. And there is nothing in this instance that will tarnish her still growing legacy.”

According to Reuters, Shields, 29, the undisputed champion in three weight classes, has been suspended from competing in the state by the Michigan Unarmed Combat Commission after an oral fluid sample was taken after her bout against Danielle Perkins on Feb. 2.
–>Claressa Shields suspended, under investigation in Michigan after positive marijuana test, per reports
The World Boxing Organization has requested a “Show notice” from Shields to provide an explanation.
The WBO does not have the authority to suspend boxers, but the Michigan Commission is conducting its own investigation to determine whether disciplinary action is necessary.
The Voluntary Anti-Doping Agency tested Shields and Perkins under the World Boxing Council Clean Boxing Program.
Desperate Claressa Shields Pens One Line After Unexpected Support Amid Michigan Suspension
Two-time Olympic gold medalist Claressa Shields isn’t happy about how she has been treated. You see, after her victory over Danielle Perkins earlier this month in Michigan, Shields tested positive for marijuana, samples for which were taken via mouth swab. The Michigan Unarmed Combat Commission immediately suspended the unbeaten boxer.
“Ms. Shields’ conduct as a licensed professional boxer constitutes an immediate threat to the integrity of professional boxing, the public interest, and the welfare and safety of professional athletes,” the Michigan commission wrote in a statement. Meanwhile, the president of the Association of Boxing Commissions Michael Mazzuli condemned the move.
He labeled the statement from the Michigan Commission “overkill” while demanding Michigan present its findings. “We would like to know what the amount of marijuana in the system was – the nanogram level,” Mazzuli said. “My understanding is it was a swab test – therefore, there is no nanogram level.”
“We feel the fighter should not be stripped of any title. In fact, numerous states and tribal commissions no longer test for marijuana and mine [the Mohegan Sun (Connecticut) commission] is one of them. The sport has to change with the industry and today’s standards,” he added. Sometime after the report, Shields hopped on to share her thoughts.
Shields expressed her gratitude for Mazzuli’s support. “Thank you! This is not how you treat a 2x Olympic Champ & 17x World champion,” she wrote. Meanwhile, Shields’ manager has also commented on the matter.
Claressa Shields’ situation is absurd, claims her manager
Claressa Shields’ manager, Mark Taffet, has slammed the Michigan Unarmed Combat Commission for calling the undefeated champion “an imminent threat to the integrity of professional boxing” over a marijuana-related suspension. Taffet called the statement “absurd” and criticized the commission for making such claims before a proper hearing. “Harmful, dangerous, horrifically inappropriate statement by a government [agency] prior to a hearing. I am incredulous,” he wrote on Facebook.
Shields, who became boxing’s first undisputed women’s heavyweight champion after defeating Danielle Perkins on February 2, denied using marijuana. Performance-enhancing drug expert Victor Conte suggested the failed test “likely would have come from second-hand smoke in the arena.” Marijuana is not considered a performance-enhancing drug and is not banned in most U.S. states. Taffet questioned Michigan’s process, stating, “We respect the process … why don’t they?” as the controversy continues to unfold.
That being said, Claressa Shields has found herself in the middle of quite the controversy, as mouth swabs revealed marijuana usage. However, what are your thoughts on the situation?
Claressa Shields isn’t letting any druggie narratives fly about her! The undisputed world champion was iced out of her sport in Michigan earlier this week, per ESPN. The state’s Unarmed Combat Commission moved to suspend and investigate Shields after a saliva swab tested positive for marijuana. Now, the boxer is denying that she ever smoked and clearing the air among her supporters by sharing her two test results.
Details On Claressa Shields’ Michigan Boxing Suspension
ESPN reports that officials took Shields’s “oral fluid sample” in early February after her win against Danielle Perkins. At the time, the test indicated the presence of weed–a banned substance in competitive sports. On Thursday (February 20), the Michigan Unarmed Combat Commission dragged Claressa Shields in their statement.
“Ms. Shields’ conduct as a licensed professional boxer constitutes an immediate threat to the integrity of professional boxing, the public interest, and the welfare and safety of professional athletes,” it reportedly stated.
While the Unarmed Combat Commission weighs whether it will take disciplinary action, the World Boxing Organization demands a formal explanation from Shields. Mind you, Claressa is a BIG DAWG in professional boxing. She is the only boxer to hold every major world title, says ESPN, from the WBA to the WBC, IBF, and WBO.
Boxer Shares Timeline Of Test Results In Social Media Clap Backs
Now that we understand what’s going on let’s get into Claressa clapping back at the marijuana allegations. She seemingly started addressing bubbling reports of her failed test last week. On Valentine’s Day, she replied to a tweet about the topic, writing, “NICE TRY HATERS DON’T Ever try and put no bullshit on me. CLEAN ATHLETES WIN,” she wrote. In a separate tweet, she seemingly labeled the drug results dispute a lie.
However, Claressa Shields has been going in the last two days about her alleged innocence. On the 20th, she spoke about why she won’t defend a lie. “On my soul can’t nobody tarnish my image. It’s a temporary suspension til I go to trial for this very small amount of marijuana. I’m not SUSPENDED from Boxing, I’m not stripped of my titles. I’m just waiting. Also, I can’t defend a lie! Do your research,” Shields tweeted.
The boxing champion thanked her supporters the following day for standing by her. She also retweeted a supportive statement from her boxing promoter, Dmitriy Salita, who denied that Claressa uses illicit drugs of any kind.
Late Friday (February 21), Claressa Shields hopped over to Instagram with her drug test results, a timeline, and an explanation. She uploaded the documents about the oral swab test, taken on the third, and the urine test, which was collected on the eighth. As mentioned, the saliva swab yielded a positive result, while the urine showed a negative result. In her caption, she wrote:
“A urine tests — the most reliable testing method — can detect weed for up to 30 days in your urine, and came back negative. The moment I received the saliva test result, I acted immediately to schedule a follow-up urine test to ensure complete clarity. These results confirm that I’ve been clean and in full compliance the entire time. I’ve always competed clean, and I stand by that. I take my integrity seriously inside and outside the ring.”
While things are getting heated regarding the ring, the same can be said for Claressa Shields’ life outside it! Though this type of heat seems more than welcomed! The champion and her new bae, Remy Ma’s estranged husband Papoose, were recently spotted still going strong in Hawai’i.
Claressa Shields has been suspended by the Michigan Unarmed Combat Commission after testing positive for marijuana following her win over heavyweight Danielle Perkins earlier this month, according to reports.
Shields, 29, tested positive for the banned substance via an “oral fluid sample” following her win over Perkins on Feb. 3, Sky News and BBC reported on Thursday, prompting the Michigan Unarmed Combat Commission to open an investigation. Shields, a native of Flint, Michigan, will not be able to compete in Michigan while suspended.
“Ms Shields’ conduct as a licensed professional boxer constitutes an imminent threat to the integrity of professional boxing, the public interest, and the welfare and safety of professional athletes,” the Michigan Unarmed Combat Commission said in a statement to Sky News.
The suspension comes less than a month after Shields made history and became the first boxer, male or female, to win undisputed titles in three different weight classes after defeating Perkins by unanimous decision on Feb. 3 at the Dort Financial Center in Flint, Michigan. Shields, a two-time Olympic gold medalist and women’s boxing champion, moved to 16-0 with three TKOs with the win.
Shields responded to the news of her suspension on X (formerly Twitter), writing, she’s “never smoked weed.” She continued, “It was marijuana, no PEDs. … it’s a temporary suspension (until) I go to trial for the very petite amount.”
In another tweet, she added, “And still the UNDISPUTED WOMENS HEAVYWEIGHT CHAMPION!”
Last week, Shields shot down rumors that she tested positive for a performance-enhancing drug, declaring she’s “been a clean athlete all my life.” She added, “To ever put my name and PEDS with positive and my name in the sentence is damaging.”
Although marijuana has been legal in Michigan since late 2018, marijuana is banned from competition by the World Anti-Doping Agency (WADA).
Feb 20 (Reuters) – American boxer Claressa Shields, the undisputed world champion in three weight classes, has been suspended and is under investigation after testing positive for marijuana following her victory over heavyweight Danielle Perkins in Michigan.
The Michigan Unarmed Combat Commission suspended the 29-year-old athlete from competing in the state after an ‘oral fluid sample’ taken after the fight on February 2 showed the presence of marijuana, which is banned in competition by the World Anti-Doping Agency (WADA).
“Ms. Shields’ conduct as a licensed professional boxer constitutes an immediate threat to the integrity of professional boxing, the public interest, and the welfare and safety of professional athletes,” the Michigan Commission said on Thursday.
The World Boxing Organization (WBO), which does not have the authority to suspend boxers, has requested a “show notice” from Shields to provide an explanation. The Michigan Commission is also conducting its own investigation to determine if disciplinary action is necessary.
Shields, the only boxer to hold every major world title – WBA, WBC, IBF and WBO – in three weight classes and a two-time Olympic gold medallist, took to social media last week posting, “Clean athletes win”.
Under the World Boxing Council Clean Boxing Program, both Shields and Perkins have been tested by the Voluntary Anti-Doping Agency (VADA).
