Usman tested positive for testosterone—a prohibited substance classified as an Anabolic Agent on the UFC’s banned list—from an out-of-competition sample collected on September 8, 2025, in his hometown of Coral Springs. The discovery triggered an immediate response from the organization, with Usman removed from a scheduled Rio de Janeiro card and placed under provisional suspension on October 9, 2025, the day he received notification of the positive result.

The 30-month suspension represents a considerable career interruption for any fighter operating at the professional level. With his ineligibility period concluding on April 9, 2028, Usman faces a lengthy absence from competition during what could have been crucial years in his fighting career. The extended length of the ban underscores CSAD and the UFC’s zero-tolerance approach to performance-enhancing drugs in combat sports.

The timing and nature of the offense add weight to the violation. Out-of-competition testing has become central to modern anti-doping protocols, designed to catch athletes using performance enhancers during training camps when they’re building strength and conditioning. The UFC, under pressure from athletic commissions and anti-doping advocates, has ramped up testing frequency in recent years. Usman’s case represents a direct consequence of that increased vigilance.

Testosterone violations carry particular stigma in MMA because they represent arguably the most fundamental form of cheating—artificially amplifying the physical attributes that determine fight outcomes. Unlike some supplement contamination cases that have resulted in reduced sentences, testosterone use suggests deliberate enhancement rather than accidental ingestion.

For Usman, the suspension effectively ends his current competitive window. Fighters rarely return to previous form after extended layoffs, particularly during prime earning years. The financial implications are severe—lost sponsorships, fight purses, and career momentum compound the competitive damage.

The case reinforces a critical message: the UFC’s testing infrastructure has teeth, and athletes operating under the assumption that out-of-competition violations might slip through the cracks do so at their peril. As the sport continues professionalizing, anti-doping compliance has become non-negotiable for anyone seeking a sustainable career in mixed martial arts.
