Already under a provisional suspension for a potential out-of-competition anti-doping violation, Gleison Tibau on Wednesday got more bad news. He is now also suspected of a potential in-competition anti-doping violation. The potential in-competition violation stems from a test sample collected immediately following his Nov. 7 victory over Abel Trujillo at UFC Fight Night 77 in Sao Paulo, Brazil. On Dec. 4, Tibau became the second fighter to be suspended for a potential Anti-Doping Policy violation under the UFC’s new policy that is being administered by the United States Anti-Doping Agency
