Claressa Shields suspended, under investigation in Michigan after positive marijuana test, per reports

Undisputed world champion Claressa Shields has been suspended and is under investigation after she tested positive for marijuana following her heavyweight victory over Danielle Perkins in Michigan, per reports.

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 the fight on Feb. 2.

The sample showed the presence of marijuana, which is banned in competition by the World Anti-Doping Agency.

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.

Shields, the only boxer to hold every major world title in three weight classes and a two-time Olympic gold medallist, posted to X after the suspension was announced.

Shields is the WBA, WBC, IBF, and WBO champion, so the news is earth-shattering, especially since she just last week posted that clean athletes win in response to Victor Conte, who is an American musician and businessman who founded BALCO.

The Voluntary Anti-Doping Agency tested Shields and Perkins under the World Boxing Council Clean Boxing Program.
