Anderson Silva's lawyer claims that a sexual performance enhancing product was tainted and led to his client's two positive tests for the performance enhancing drug Drostanolone, according to Combate.

Silva, 40, will share his reasoning for his positive test ahead of UFC 183 in Jan. with the Nevada State Athletic Commission during a disciplinary hearing on Thursday. Silva tested positive on the day of his fight against Nick Diaz and during an out-of-competition test on Jan. 9, which showed banned substance androstane in his system.

Post-fight drug tests found sleeping aid temazepam and anti-anxiety medication oxazepam in his system. The two substances are not illegal to use if disclosed on a pre-fight questionnaire and approved by commissioner Jeff Blatnick, which Silva did not do.

His lawyer shared a 27-page defense on Wednesday, in which he states that Silva was “administering or using a supplement for the purpose of enhancing sexual performance and testing of the supplement revealed that the supplement was contaminated with an Exogenous Anabolic Agent: Drostanolone metabolite.”

Silva could face a lengthy suspension from the sport.
