Claressa Shields, a 29-year-old US-born boxer and the only fighter to hold undisputed world titles in three weight classes, has been suspended by the Michigan Unarmed Combat Commission after testing positive for marijuana. The suspension follows an “oral fluid sample” collected after her February 3 victory over Danielle Perkins in Michigan, which revealed the presence of the banned substance.
