All 10 fighters who underwent drug testing before and after this past weekend's UFC 108 event tested clean for performance-enhancing drugs and recreational/drugs of abuse.
Nevada State Athletic Commission Executive Director Keith Kizer today e-mailed the drug-testing results to MMAjunkie.com.
UFC 108 took place Jan. 2 at the MGM Grand Garden Arena in Las Vegas. Rashad Evans edges Thiago Silva via decision in the night's pay-per-view headliner.
Both Evans and Silva were tested prior to the show in December as part of the NSAC's year-round drug-testing option. Additionally, the NSAC on fight night tested Evans, Paul Daley, Sam Stout, Jim Miller, Junior Dos Santos, Martin Kampmann, Mark Munoz, Jake Ellenberger and Rafaello Oliveira. All tested negative.
All fighters were tested for drugs of abuse (such as marijuana and cocaine), as well as anabolic steroids and other performance-enhancers.
In addition to fight night, MMA fighters are subject to drug testing at any time – for just about any reason – throughout the year, regardless of whether or not the fighter is scheduled for an upcoming event. However, the testing is usually reserved for scheduled competitors.
