Fifteen of the 22 fighters that competed on the UFC 125: Resolution fight card on New Year’s Day were drug tested by the Nevada State Athletic Commission, according to Keith Kizer, the commission’s executive director.
Of those 15, however, only 14 of them are confirmed as testing negative, meaning that they were cleared of any use of banned performance enhancing or recreational substances. The 14 fighters on the all-clear list are: Frankie Edgar, Gray Maynard, Chris Leben, Brian Stann, Brandon Vera, Phil Baroni, Thiago Tavares, Jeremy Stephens, Dustin Poirier, Diego Nunes, Daniel Roberts, Jacob Volkmann, Dong Hyun Kim and Clay Guida.
Kizer stated that they were “still processing another athlete’s urine sample from that event.” An earlier report by MMAJunkie.com, before the NSAC released the names of the cleared fighters, stated that while Kizer would not confirm that Silva’s sample was being questioned, “the NSAC executive did confirm that Silva was among the UFC 125 fighters who submitted a pre-fight screen.” After the list of cleared fighters came out, Kizer confirmed to MMAWeekly.com that the sample still being processed was indeed that of Thiago Silva.
The typical reasoning for such a lengthy processing time is a questionable result. The pre-fight drug screens in Nevada are processed by a WADA certified laboratory, which requires an A and B sample for each test. If the A sample returns a questionable result then the B sample is tested to verify those findings, lengthening the amount of time for definitive results.
Multiple MMAWeekly.com sources on Wednesday indicated that Silva was out of a planned fight with Quinton “Rampage” Jackson at UFC 130 in May. Those sources did not declare why Silva was out, but a failed drug test would be one reason. If he were to test positive, Silva would be under an immediate suspension that would make him ineligible.
Sources also indicated that Rashad Evans, recently forced out of his UFC 128 title fight with Mauricio “Shogun” Rua due to a minor injury, would be healed in time and is stepping in to fight Rampage at UFC 130.
