Brazilian fighter Thiago Tavares has tested positive for the use of a performance enhancing drug prior to his loss at UFC on FX 7 in Brazil last month, according to Brazil’s TATAME.

Tavares, who lost to Khabib Nurmagomedov, tested positive for the drug Drostanolone, which is an anabolic steroid.

The news comes as many in the media suspected it was the event’s headliner Vitor Belfort that had tested positive for use of PEDs, given his suspected history. Belfort was however given a TUE (therapy use exemption) for testosterone replacement treatment (TRT) in the build-up to his victory over Michael Bisping.

Zuffa released a statement on Wednesday dispelling any rumors suggesting Belfort had done any wrong.

“To dispel rumors that have been circulated, Zuffa wishes to clarify that Vitor Belfort’s drug test results were negative and did not indicate the presence of any performance enhancing drugs.

Belfort has been on a medically approved testosterone replacement therapy (TRT) regimen under the supervision of a medical doctor from the State of Nevada, after being diagnosed with hypogonadism, or low testosterone. The purpose of a medically administered TRT regimen is to allow patients with hypogonadism to maintain testosterone levels within a range that is normal for an adult male.”

With the news that Belfort was on TRT for his last fight, expect an irate Bisping to plead his case for a rematch should he successfully navigate his upcoming April bout with Alan Belcher.
