The 11 fighters who were randomly chosen to undergo drug testing earlier this month at UFC Fight Night 14 (also dubbed "UFC: Silva vs. Irvin") have tested negative for performance-enhancing drugs and drugs of abuse.
The event featured UFC middleweight champion Anderson Silva's non-title, light-heavyweight win over James Irvin. Both headliners were tested, as were Tim Credeur, Cale Yarbrough, Hermes Franca, Frankie Edgar, Cain Velazquez, Brandon Vera, C.B. Dollaway, Nate Loughran and Shannon Gugerty.
