The United States Anti-Doping Agency (USADA) announced yesterday in a press release that UFC bantamweight Francisco Rivera (11-7-0, 1NC) has been suspended for four years following a positive test from a out-of-competition sample on July 23, 2016.
Rivera, 36, tested postitive for Clenbuterol, an anabolic agent which is prohibited at all times under the UFC Anti-Doping policy.
According to USADA, Rivera’s explanation of meat contamination did not correspond to the levels found, nor was he able to provide independent evidence to support that he had ingested tainted meat in Northern Mexico days before the sample collection.
In addition, evidence was found that “several pieces of evidence presented by Rivera to USADA and the arbitrator had been falsified to support the athlete’s claims that the substance had originated from contaminated meat in Mexico.”
Rivera’s last fight was a decision loss to Erik Perez at UFC 201 in July 2016.
His suspension began on August 17, 2016.
