Antonio “Bigfoot” Silva failed the post-fight drug test following his recent war with Mark Hunt, officials confirmed on Tuesday.

Silva had been issued a therapeutic use exemption for TRT, but his levels were higher than allowed in the post-fight test.

“All fighters on the UFC Fight Night card were drug tested by an independent third-party laboratory at the event and all fighters passed their drug tests with the exception of Antonio “Bigfoot” Silva,” the UFC said in a statement. “Although Silva is on a medically approved regimen of Testosterone Replacement Therapy (TRT), and had been in compliance with therapeutic guidelines on all pre-fight tests performed prior to the event, the results of his test on the day of the event indicated a level of testosterone outside of allowable limit.”

Silva and Hunt fought to a majority draw in Australia, with each earning $50,000 for “Fight of the Night” honors.

The fighter took to Facebook to try and clear up the issue.

“Months before my fight I looked for the UFC doctor Marcio Tannure in Brazil so I could start the hormonal replacement “TRT” which was authorized and recognized by a professional,” Silva said on Facebook. “I started the treatment and 2 weeks before my fight I did all the exams required by the UFC.

“My testosterone level continued to be low so I was recommended by the doctor to increase the dosage. Unfortunately my level increased too much and caused me to suspend. I only did what was recommended by someone trained who understands about the subject therefore it was not my mistake. I’m cool because I know that the mistake was not made by me, I never tried doing anything wrong for my fight.”
