"The UFC organization was notified today that the U.S. Anti-Doping Agency (USADA) has informed Francisco Rivera of a potential Anti-Doping Policy violation stemming from an out-of-competition sample collection on July 23, 2016. "USADA, the independent administrator of the UFC Anti-Doping Policy, will handle the results management and appropriate adjudication of this case. It is important to note that, under the UFC Anti-Doping Policy, there is a full fair legal 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." http://www.ufc.com/news/UFC-Statement-on-Francisco-Rivera-081716
