LAS VEGAS -- The Nevada State Athletic Commission continues to implement its enhanced drug-testing policy ahead of major UFC events.

NSAC executive director Bob Bennett confirmed to ESPN.com that the commission has ordered multiple random blood tests on UFC light heavyweight champion Jon Jones and title challenger Daniel Cormier. The two are scheduled to headline a UFC 182 pay-per-view event on Jan. 3 at the MGM Grand Garden Arena.

Thus far, blood samples submitted by Jones (20-1) and Cormier (15-0) have produced negative results. The NSAC is awaiting the results of a second test.

Bennett also confirmed that newly crowned UFC welterweight champion Robbie Lawler and Johny Hendricks were tested ahead of their title fight at UFC 181 on Dec. 6. All test results were negative.

Lawler (25-10) defeated Hendricks (16-3) via split decision to claim the 170-pound crown. The NSAC also randomly blood-tested Lawler, 32, ahead of a bout against Jake Ellenberger at UFC 173 in May.
