Claressa Shields suspended after positive marijuana test in Michigan

Claressa Shields, the undisputed women's boxing champion, has been suspended by the Michigan Unarmed Combat Commission after testing positive for marijuana following her victory over Danielle Perkins. This suspension threatens her historic achievement of becoming the first boxer to unify titles in three weight classes during the four-belt era. The commission stated that Shields' conduct poses an imminent threat to the integrity of professional boxing and the welfare of athletes. The World Boxing Organization has also requested Shields to provide an explanation for the positive test, although they lack the authority to impose suspensions. Shields, who has previously asserted her status as a 'clean athlete,' now faces scrutiny amid an ongoing investigation into the circumstances surrounding the test. The positive result comes as many athletic commissions are reconsidering the status of marijuana as a banned substance in sports.
