Mohammed Usman has spoken publicly for the first time since receiving a lengthy suspension from Combat Sports Anti-Doping. On Friday, CSAD announced that Usman tested positive for testosterone ahead of a scheduled Oct. 11 heavyweight bout with Valter Walker at UFC Rio. The positive test forced Usman out of the fight, and the investigation later revealed he also admitted to using the banned peptide BPC-157 earlier in 2025.
As a result, Usman was handed a 30-month suspension and is ineligible to compete until April 2028. Following the announcement, the 36-year-old released a statement on Instagram, offering an apology and taking responsibility for the violation.
