UFC officials released the following statement. “USADA, the independent administrator of the UFC Anti-Doping Policy, will handle the results management and appropriate adjudication of this case,” the statement read. “It is important to note that, under the UFC Anti-Doping Policy, there is a full and fair review process that is afforded to all athletes before any sanctions are imposed. Additional information will be provided at the appropriate time as the process moves forward.” Rivera (11-7) who recently lost by unanimous decision to Erik Perez at UFC 201, spoke to MMAFighting to give his side of the story and released a statement through his management group Iridium Sports. Rivera, 34, said he was vacationing in Mexico just before the drug test, which is significant in this case. The World Anti-Doping Agency (WADA) issued a warning in 2011 that said China and Mexico have a “serious problem” with meat contaminated with clenbuterol, which is clinically used in some countries to treat breathing disorders in humans. Rivera said he ate meat on multiple occasions when he was in Mexico. If USADA determines that Rivera take the drug on purpose, he could face a two-year suspension. UFC 202 Embedded: Episode 5
