UFC 146 drug test results come back clean for 'Dos Santos vs Mir' on May 26 in Las Vegas

UFC 146 drug test results are in from the Nevada State Athletic Commission (NSAC), who today confirmed that all 24 fighters tested for illegal/banned substances after competing at the "Dos Santos vs. Mir" pay-per-view (PPV) event back on May 26, 2012 in Las Vegas have all passed with flying colors.

Each combatant was screened for performance enhancers such as steroids and drugs of abuse like cocaine and marijuana, among others.

Results from these battery of tests all returned negative.

UFC 146 featured the first successful title defense of heavyweight champion Junior dos Santos, who planted former division titleholder Frank Mir en route to a technical knockout victory.

Could we be looking at another dominant reign from a Brazilian striker?

Cain Velasquez might have something to say about that, especially considering he earned himself a possible rematch against "Cigano" by utterly dismantling Antonio Silva in the co-main event of the evening.
