UFC releases statement on Gleison Tibau's 2nd drug test failure from Trujillo fight

The U.S. Anti-Doping Agency (USADA) has notified the UFC of another potential drug test failure for Gleison Tibau. This violation stems from a post-fight drug test sample taken on the night of his win over Abel Trujillo in November.

It is the second time that Tibau has been flagged for a possible drug test failure for his fight with Trujillo. He was notified earlier in December that he had failed an out of competition drug test, testing positive for EPO, a performance enhancing drug.

The 32-year-old Tibau was provisionally suspended by the UFC after the apparent failed drug test. In a statement on their website, the UFC added that further actions will be taken and additional information will be given at an appropriate time. Under the new UFC-USADA anti-doping rules, a first time offense for PED use is a 2-year ban.

Tibau released a statement after the first possible drug test failure, saying that he has not knowingly taken any performance enhancing supplements.

Tibau's win over Trujillo could be overturned and changed to a No Contest if the positive drug tests are confirmed. Tibau submitted Trujillo by rear-naked choke in the first round, but the finish was controversial. The referee stepped in and stopped the fight during the choke while Trujillo continued to defend, with no sign of a verbal or physical tap out from Trujillo.
