According to multiple reports, the former middleweight champ Silva allegedly tested positive for Drostanolone metabolites, in a pre-fight drug test he was submitted. The results of the pre-fight test reportedly did not come in until Tuesday.
Diaz, on the other hand, has tested positive for marijuana metabolites in a post fight drug test.
The UFC has released follow up statements regarding the drug tests of both fighters. The statement regarding Silva relayed:
“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. 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. UFC is disappointed to learn of these initial results.
“The UFC has a strict, consistent policy against the use of any illegal and/or performance enhancing drugs, stimulants or masking agents by its athletes.”
The statement regarding Diaz’s drug test was the following:
“The UFC has been notified by the Nevada State Athletic Commission that Nick Diaz has tested positive for marijuana metabolites following his fight with Anderson Silva at UFC 183 on Jan. 31 in Las Vegas, Nev. The UFC has a strict, consistent policy against the use of any illegal and/or performance enhancing drugs, stimulants or masking agents by our athletes. As a result of his positive test, Diaz has been informed that he has violated the UFC Fighter Conduct Policy and Promotional Agreement with Zuffa, LLC. The UFC organization will fully respect the Commission’s final decision relating to Diaz at a disciplinary hearing set for February 17.”
Silva scored a unanimous decision win over Diaz at the January 31st event, which went down at the MGM Grand Garden Arena in Las Vegas.
After the bout, the soon to be 40 year-old star said he would discuss his future with his family, before he commits to another fight. In light of these latest developments, however, the former middleweight champ could be sidelined for the remainder of 2015.
