What was hailed as one of the greatest heavyweight battles of all time has now been tainted. Antonio “Bigfoot” Silva, who scrapped with Mark Hunt at UFC Fight Night 33 on December 7 in a knockdown, drag-out five-round war, has been busted for elevated testosterone levels in his post-fight screening.

FightLine has got the deets:

“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.”

Bigfoot and Hunt fought to a majority draw, with both men netting a $50,000 Fight of the Night bonus for their efforts. With his failed drug test, the Brazilian behemoth’s record will no reflect a “no contest” (Hunt’s record will still show a majority draw). In addition, that 50K Silva earned? It now goes to Hunt.

UFC President Dana White released this statement on this sad turn of events:
