UFC 166: Velasquez vs. dos Santos 3 Official Weigh-in Results

The drug test results for UFC 155: dos Santos vs. Velasquez II are in with all fighters returning negative results.

Nevada Athletic Commission executive director Keith Kizer informed that all 24 combatants were drug tested, and that all 24 returned negative results. The test checks for performance enhancing substances, as well as recreational drugs.

The heavyweight championship rematch between Junior dos Santos and Cain Velasquez headlined the Dec. 29 UFC 155 fight card at the MGM Grand Garden Arena in Las Vegas.

Velasquez dominated the fight, brutalizing dos Santos for all five rounds, but couldn’t put the stubborn Brazilian away.

Lightweights Jim Miller and Joe Lauzon, however, stole the show with their bloody, three-round Fight of the Night performance.

UFC 155 marked the promotion’s second event held in Las Vegas in December. All 22 fighters on the TUF 16 Finale on Dec. 15 were also drug tested, with all 22 returning negative results.

The Octagon returns to Las Vegas for UFC 156 on Feb. 2 for the promotion’s Super Bowl Weekend event featuring Jose Aldo vs. Frankie Edgar and Alistair Overeem vs. Antonio “Bigfoot” Silva.
