USADA announced Thursday that it has suspended the UFC lightweight veteran for two years for failing both in- and out-of-competition drug tests in the fall. Tibau tested positive for erythropoietin (EPO) in both tests, USADA said.
The Brazilian told MMA Fighting earlier this week that he had dropped his appeal and would accept the USADA sanctioning.
Tibau, 32, defeated Abel Trujillo via first-round submission at UFC Fight Night: Belfort vs. Henderson 3 on Nov. 7, 2015. That win will be overturned into a loss, according to the USADA release. The bout happened in Sao Paulo, Brazil and USADA said that the Brazilian MMA Athletic Commission (CABMMA), which holds jurisdiction there, will recognize the USADA sanction.
