UFC competitor George Sullivan voluntarily disclosed information to the U.S. Anti-Doping Agency (USADA) that could pose a potential compliance issue with the UFC Anti-Doping Policy. Out of an abundance of caution, Sullivan has been removed from his scheduled bout on Saturday night against Hector Urbina while USADA conducts an investigation into the matter.

Urbina will still weigh in as a potential backup opponent should there be a need for him to compete in another bout on Saturday. Otherwise, he will be re-booked for another card in the near future.
