The UFC 147: Silva vs. Franklin II drug test results are in and they all came back clean.
All 22 fighters at UFC 147 were tested for both illegal recreational drugs as well as performance enhancing drugs. The results were negative for all 22 fighters, according to UFC vice president of regulatory affairs Marc Ratner.
Since UFC 147 took place at an international location without a regulatory body, the UFC coordinated with an independent testing company to provide for drug testing of its athletes.
Wanderlei Silva and Rich Franklin headlined the event, which also included the featherweight and middleweight finals of the inaugural season of The Ultimate Fighter: Brazil.
