On August 13, after several reschedules, the disciplinary hearing was held to decide on the subject. Silva's defense argued that a tainted sexual enhancement supplement was the root of the two failed tests for drostanolone and also appealed to mistakes in the NSAC testing procedures, pointing to a pair of drug tests, one on Jan. 19 and one after the fight, which Silva passed. He admitted to using both benzodiazepines the night prior to the fight as therapy to control stress and help him sleep. Silva's team was unable to explain the presence of androsterone in the Jan. 9 test. The commission rejected the defense and suspended him for one year retroactive to the date of the fight, as the current guidelines were not in effect at the time of the failed tests. He was also fined his full win bonus, as well as 30% of his show money, totaling $380,000. His victory was overturned to a no contest.  Diaz's hearing was delayed until September.  On September 14, Diaz was suspended for five years and also fined 33% of his show purse totaling $165,000.  Following his appeal four months later in January 2016, the suspension and fine were reduced to 18 months and $100,000 respectively.
