UFC light heavyweight champion Jon Jones has entered drug treatment, the mixed martial arts promotion says.

The UFC announced Tuesday that Jones failed a random drug test last month.

The Nevada Athletic Commission says Jones tested positive for the main metabolite of cocaine, according to Yahoo Sports.

Benzoylecgonine is not banned by the commission for out-of-competition use, so Jones wasn’t penalized or suspended.

Jones defeated Daniel Cormier by unanimous decision at UFC 182 in Las Vegas last Saturday night.

The 27-year-old Jones (21-1) is considered the world’s best pound-for-pound MMA fighter. His victory over Cormier, a previously unbeaten contender, was his eighth consecutive title defense since winning the belt in March 2011.
