George Sullivan has been notified by USADA of a potential Anti-Doping violation and has been provisional suspension based on his declaration of a prohibited substance.

The potential Anti-Doping violation was announced by the UFC in a statement on Wednesday evening.

“UFC was made aware today by the U.S. Anti-Doping Agency (USADA), the independent administrator of the UFC Anti-Doping Policy, that it has informed George Sullivan of a potential anti-doping violation and provisional suspension based on his declaration of a prohibited substance,” the UFC statement said. “UFC previously announced that Sullivan voluntarily disclosed this information to USADA and, out of an abundance of caution, Sullivan was removed by UFC from his scheduled bout on July 23, 2016, in Chicago. Under the UFC Anti-Doping Policy, Sullivan’s declaration of the use can be taken into consideration by USADA during the results management and adjudication process.”

“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, a full and fair legal review process is afforded to all athletes before any sanctions are imposed.”

Sullivan (17-5, 1NC) was signed by the UFC in early 2014 and has gone 3-2 in the promotion. His last fight took place at UFC on FOX 18 in January as he was defeated by Alexander Yakovlev.
