A superfight between GSP and Silva would be ‘bigger than UFC 100’

The post-fight drug test continues to be Nick Diaz's toughest opponent.

Following a unanimous decision loss to Anderson Silva at UFC 183 on Saturday night in Las Vegas, Diaz tested positive for marijuana metabolites, Nevada Athletic Commission (NAC) executive director Bob Bennett confirmed with MMAFighting.com's Ariel Helwani on Tuesday. Yahoo's Kevin Iole initially reported the results.

Diaz had more than the allowed maximum of 150 nanograms of the metabolites in his system. He'll be temporarily suspended and will have to appear before the NAC in order to be relicensed to fight.

This is Diaz's third time testing positive for weed in his career. He popped for marijuana after a loss to Carlos Condit at UFC 143 and was also suspended in Nevada then. Diaz's 2007 win over Takanori Gomi was overturned into a no contest and he was suspended again for failing a test for pot.



Silva also failed a drug test, a Jan. 9 out-of-competition screening for drostanolone, an anabolic steroid, and androsterone, a steroid hormone. He, too, is temporarily suspended.
