TUF 16 Finale drug test results come back clean for 'Nelson vs Mitrione' on Dec. 15 in Las Vegas

VADA who?

The Ultimate Fighter (TUF) 16 Finale drug test results are in from the Nevada State Athletic Commission (NSAC), which today confirmed that all 24 fighters tested for illegal/banned substances after competing at the "Nelson vs. Mitrione" mixed martial arts (MMA) event on Dec. 15, 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.

TUF 16 Finale featured Roy Nelson taking on Matt Mitrione in the main event of the evening because his opposing coach on this season of TUF, Shane Carwin, was forced off the card because of an injury. "Big Country" didn't seem fazed with the late replacement, needing less than five minutes to score a decisive knockout finish (watch it here) and the opportunity to rub 'dat belly in victory.

Elsewhere on the card, Colton Smith was crowned the latest TUF winner, overwhelming his fellow welterweight finalist, Mike Ricci, for nearly three full -- and hard-to-watch -- rounds.
