Anderson Silva, Nick Diaz failed drug tests
The MMA community was in shock Monday when news surfaced that UFC 183 headliners Anderson Silva and Nick Diaz, who met Saturday at Las Vegas’ MGM Grand Garden Arena, in which Anderson Silva defeated Nick Diaz via unanimous decision on January 31st at UFC 183 however both failed drug tests.
Silva (36-4 MMA, 17-2 UFC) was flagged for Androsterone and Drostanolone metabolites stemming from a random pre-fight test. Diaz’s (26-10 MMA, 7-7 UFC) post-fight test showed marijuana metabolites.
Official statement from the UFC reads as follows:
“On February 3, 2015, the UFC organization was notified by the Nevada State Athletic Commission that Anderson Silva tested positive for Drostanolone metabolites on his Jan. 9 out of competition drug test,” read a UFC statement.
UFC’s understanding is that further testing will be conducted by the commission to confirm these preliminary results.
“Anderson Silva has been an amazing champion and a true ambassador of the sport of mixed martial arts and the UFC, in Brazil as well as around the world. We are disappointed to learn of these initial results.”
Anderson Silva not only tested positive for Drostanolone metabolites in a January 9th out-of-competition drug test, but traces of the banned substance Androsterone were also found in the legendary champion’s system, according to Nevada Athletic Commission (NAC) executive director, Bob Bennett.
Drostanolone is a common form of anabolic steroid. Androsterone is a form of endogenous testosterone. Both substances are banned according to the World Anti-Doping Agency code.
According to Bennett, Silva was tested out-of-competition on January 9th, then January 19th with an in-competition test. Another in-competition test was administered on January 31st. Silva passed the latter two tests according to Bennett.
“I think it’s very unfortunate,” Bennett told MMAfighting.com‘s Ariel Helwani. “The UFC have made a tremendous effort to level the playing field in their fight against Performance Enhancing Drugs (PEDs). Credit goes to them for doing the right thing based on principles and they continue to support our out-of-competition drug testing efforts.
Bennett added that the NAC’s new objective will be to receive out-of-competition drug test results within a week, and that the commission is at this point not aware of Silva failing any other tests other than the one administered on January 9th.
Of the two, Silva’s is the more severe infraction. Drostanolone is an anabolic steroid that is most regularly used by bodybuilders to reduce fat, per EliteFitness.com. It lowers water retention, which cuts weight and allows for a more toned physique. Silva’s positive test is interesting because it comes not long after he called for a lifetime ban on performance-enhancing drug users.
