Wow! This is pretty shocking news in regard to the drug test results of both fighters who headlined UFC 183 over the weekend. Actually, it’s much more shocking on Anderson Silva’s end since he never failed a drug test in the UFC before.
On January 9th, Silva tested positive for the anabolic steroid, drostanolone, in an out-of-competition drug test conducted by the Nevada Athletic Commission (NAC). As far as Nick Diaz goes, his results showed elevated levels of marijuana metabolites in his system after UFC 183. This is the third time Diaz has been caught with this kind of substance in his blood throughout his MMA career.
The UFC released the following statement about Silva’s result:
