The UFC released a statement on Friday announcing that the Brazilian veteran has been 'provisionally suspended' due to a potential failed out-of-competition drug test. The news comes less than a month after Tibau's Nov. 7 victory over Abel Trujillo at UFC Fight Night 77, which was his 17th in the promotion.
The UFC's statement can be read below:
The U.S. Anti-Doping Agency (USADA) has notified both Gleison Tibau and UFC that he has been provisionally suspended due to a potential Anti-Doping Policy violation stemming from an out-of-competition test.
USADA, the independent administrator of the UFC Anti-Doping Policy, will handle the results management and appropriate adjudication of this case involving Gleison Tibau.
