It’s not looking good for UFC lightweight veteran Gleison Tibau.

In addition to potentially failing an out-of-competition drug test, Tibau is now facing a potential Anti-Doping violation from a sample collected in-competition.

The UFC released the following statement:

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.

The Brazilian is already serving a provisional suspension from USADA for failing an out-of-competition drug test following his first round submission win over Abel Trujillo at UFC Fight Night 77 in November.

The substance for which the lightweight fighter tested positive has not been named.
