---

All drug tests conducted at UFC 167 came back negative, according to the Nevada Athletic Commission.

NAC Executive Director Kizer informed Sherdog.com of the results on Friday, revealing that all fighters who competed at the Nov. 16 event were subject to testing.

UFC 167 took place at MGM Grand Garden Arena in Las Vegas and was headlined by a welterweight title showdown between Georges St. Pierre and Johny Hendricks. St. Pierre held onto his title in a hotly contested split decision, defending his belt successfully for the ninth straight time.

The pay-per-view event also saw former light heavyweight champion Rashad Evans dominate ex-title challenger and broadcast partner Chael Sonnen, stopping the 36-year-old in the first round with strikes from the back mount. Earlier, welterweight standouts Robbie Lawler and Tyron Woodley both picked up impressive victories, besting Rory MacDonald and Josh Koscheck, respectively.
