UFC heavyweight Mohammed Usman has accepted a lengthy suspension after admitting to testosterone use.
Combat Sports Anti-Doping (CSAD) announced Friday that Usman (11-4 MMA, 4-2 UFC) tested positive for testosterone, a substance on the UFC Anti-Doping Policy (UFC ADP) prohibited list. The out-of-competition sample was collected on Sept. 8, 2025, in Coral Springs, Fla. Usman was scheduled to compete against Valter Walker at UFC Fight Night 261 on Oct. 11, 2025, in Rio de Janeiro, Brasil, but was removed from the bout due to the positive test.

Usman has accepted a 30-month suspension.
CSAD stated in the release that Usman eventually admitted to the use of testosterone ahead of the event and prior use of BPC-157, a prohibited peptide. CSAD explained that Usman initially attempted to deceive them with a false explanation for the positive test, which prompted a strict response. Due to Usman’s attempts to deceive, CSAD could have doubled the standard two-year suspension, but settled on a six-month addition, totaling 30 months after Usman ultimately admitted fault.
The suspension is backdated to Oct. 9, 2025, and will end on April 9, 2028.
