Earlier this month it was revealed that Gleison Tibau had been suspended for blood doping. Tibau subsequently released a statement in which he apologized for his actions, and also offered Abel Trujillo a rematch.

Now, according to UFC.com, Tibau has failed a second drug test, this time an in-competition one.

“The U.S. Anti-Doping Agency (USADA) has notified both Gleason Tibau and UFC of a potential Anti-Doping Policy violation stemming from an in-competition sample collected immediately after his bout in Sao Paulo, Brazil on November 7, 2015. Tibau and UFC were previously notified that he had 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 Tibau. Additional information will be provided at the appropriate time as the process moves forward.”

Only time will tell if Tibau’s back to back failed drug tests earn him a suspension similar to that of Nick Diaz, who didn’t actually use PEDs.
