UFC Light Heavyweight Champion tested positive for cocaine metabolites last month and has entered a rehabilitation facility, according to a report from MMA Junkie.

According to Nevada Athletic Commission Executive Director Bob Bennett, Jones failed a random test on December 3, who noted that Jones has checked in to “a rehab center.”

There is no word on whether the result from Jones’ last bout, a victory over hated rival Daniel Cormier at UFC 182 in Las Vegas on Saturday, will be overturned. That win represented Jones’ eighth consecutive defense of the UFC Light Heavyweight Championship, the most in that division’s history.

Only Georges St-Pierre and Anderson Silva recorded more consecutive title defenses, at 8 and 10 respectively.

UFC gave the following on their official site:

“We support UFC light heavyweight champion Jon Jones’ decision to enter a drug treatment facility to address his recent issue. While we are disappointed in the failed test, we applaud him for making this decision to enter a drug treatment facility. Jon is a strong, courageous fighter inside the Octagon, and we expect him to fight this issue with the same poise and diligence. We commend him on his decision, and look forward to him emerging from this program a better man as a result.”

UFC President Dana White offered the following statement:

“I am proud of Jon Jones for making the decision to enter a drug treatment facility. I’m confident that he’ll emerge from this program like the champion he truly is.”
