Following an action packed night of fights at UFC 156, the Nevada State Athletic Commission has released the drug testing results from the Feb. 2 card in Las Vegas.
According to Nevada State Athletic Commission Executive Director Keith Kizer, all 22 fighters on the card were tested and all tests came back negative.
UFC 156 featured a main event pitting featherweight champion Jose Aldo against former lightweight title holder, Frankie Edgar. After a back and forth battle for five rounds, Aldo came away the victor with a successful title defense.
The fighters on the card are tested for performance enhancing drugs (steroids, etc) as well as drugs of abuse (marijuana, cocaine, etc).
The card featured the return of former K-1 and Strikeforce champion Alistair Overeem, who was in the center of a drug testing scandal in 2012 that prevented him from competing for the UFC heavyweight title.
Prior to his scheduled bout at UFC 146 in 2012 against then champion Junior Dos Santos, Overeem failed a pre-fight screening for having elevated levels of testosterone. Overeem was removed from the fight and eventually was denied a fight license by the commission and handed a de facto 9-month suspension.
During the time he was absent from the sport, Overeem was involved in several out-of-competition drug tests, with all coming back negative. His test taken at UFC 156 by the Nevada State Athletic Commission has now also come back negative as well.
While his tests came back clean, Overeem unfortunately suffered a loss on the card to Antonio "Bigfoot" Silva that likely cost him a shot at the UFC heavyweight title. Silva is now in position to face champion Cain Velasquez later this year at UFC 160.
Just last week the UFC returned a positive drug test from the UFC on FX 7 in Brazil, where lightweight fighter Thiago Tavares was suspended for nine months for having Drostanolone, an anabolic steroid, in his system.
