Very little information was released regarding the potential doping violation, but the 32-year-old is facing at least a two-year ban.
“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,” the UFC expressed in a statement. “USADA, the independent administrator of the UFC Anti-Doping Policy, will handle the results management and appropriate adjudication of this case involving Gleison Tibau. Additional information will be provided at the appropriate time in the process.”
Tibau was seen last month submitting Abel Trujillo at UFC Fight Night 77.
