UFC 167 drug test results come back clean for 'St. Pierre vs. Hendricks' event on Nov. 16 in Las Vegas

UFC 167 drug test results are in from Nevada State Athletic Commission (NSAC), which today (Nov. 22, 2013) confirmed that all 24 mixed martial arts (MMA) fighters who were tested for illegal/banned substances after competing at the "St. Pierre vs. Hendricks" pay-per-view (PPV) event on Nov. 16 in Las Vegas, have all passed with flying colors.

Each combatant was screened for performance enhancing drugs such as steroids, as well as drugs of abuse like cocaine and marijuana, among others. Results from these battery of tests all returned negative.

Then again, we already knew that for at least one main card fighter.

UFC 167 headliners Georges St-Pierre and Johny Hendricks were involved in a "stupid" squabble about who could pee the cleanest ahead of their welterweight championship contest last weekend in "Sin City." Turns out everyone was a winner, since there were no violations.

Still, some fighters insist on going above and beyond the call of duty, like Travis Browne, who joined opponent Josh Barnett for random World Anti-Doping Agency (WADA) drug testing ahead of their titanic tilt at next month's UFC 168 PPV event (details), also in Las Vegas.
