Not much of a surprise here.

Gleison Tibau, already provisionally suspended after an out-of-competition violation of the UFC's anti-doping policy, has also violated the policy with an in-competition sample after UFC Fight Night: Belfort vs. Henderson 3 last month in Sao Paulo, Brazil, the UFC announced Wednesday

The UFC said in a statement that USADA, which runs its anti-doping program, notified both Tibau and the promotion of the violation this week. Tibau beat Abel Trujillo on the Nov. 7 card via first-round submission.

Tibau (34-11), one of the winningest fighters in UFC history, was provisionally suspended by after a possible USADA out-of-competition violation on Dec. 4. In a statement, the Brazilian fighter said he tested positive for recombinant human erythropoietin (EPO), but seemed to deny knowingly taking any kind of performance-enhancing drug.

"As a responsible man that I am, I never believed I ingested something that could fantasize my performances," Tibau said. "I make sure I have a healthy life outside the sport, and honest and clean inside the sport. I train hard, I do my best."

USADA will handle the results management and adjudication of Tibau's case. Mirko Cro Cop has already received a two-year suspension for admitting to using human growth hormone. Tibau's victory over Trujillo is also likely in jeopardy.

Tibau, 32, has won four of his last five fights and 17 UFC bouts total. He has fought for the promotion since 2006.
