Four UFC fighters have been suspended six months by USADA, all for testing positive for the banned substance ostarine, the UFC’s anti-doping partner announced Tuesday.
The four fighters were former UFC women’s flyweight champion Nicco Montaño, prospect Sean O’Malley, Augusto Mendes and Marvin Vettori. All had trace amounts of ostarine in their system in drug tests last year, which USADA says is consistent with supplement contamination. USADA found “no evidence of intentional use” in any of the four cases, per a release.
“The trace amounts of ostarine found in each of the athlete’s samples was made possible by sensitive laboratory detection capabilities,” USADA stated in a press release.
