Mohammed Usman, former UFC champion’s brother, suspended 30 months for doping violation
Mohammed Usman, the 36-year-old younger brother of former UFC welterweight champion Kamaru Usman, accepted a 30-month suspension after testing positive for the illegal substance, testosterone, prior to a UFC Rio bout with Valter Walker in October 2025, Combat Sports Anti-Doping (CSAD) announced Friday. Usman also confessed to the use of banned peptide BPC-157 earlier that year.
“While Usman ultimately took responsibility for the above details, he did not do so in a timely fashion and not until CSAD confronted him with evidence they had independently collected during a detailed investigation of his use of these multiple prohibited substances as well as his attempt to deceive CSAD with a false explanation,” the release said.
According to the agency, “if a UFC athlete uses multiple substances like Usman did and engages in deceptive or obstructive conduct to avoid the adjudication of an Anti-Doping Policy Violation like he did, then aggravating circumstances are determined to exist.” Therefore, CSAD decided it was “appropriate” to add six months to the standard 2-year suspension “for these aggravating factors.”
The former Ultimate Fighter winner will be 39-years-old when his suspension ends in April 2028. Usman last fought in June 2025, when he won a decision over Hamdy Abdelwahab to bring his promotional record to 4-2.
