UFC light-heavyweight champion Jon Jones has entered a drug treatment facility, the fighter announced Tuesday.

Jones tested positive for benzoylecgonine, which is the main metabolite for cocaine. That occured on Dec. 4, according to Yahoo! Sports. It is considered out of competition, so under the World Anti-Doping Agency code that the Nevada Athletic State Commission abides by, Jones couldn't be suspended.

Jones is coming off perhaps his signature victory last Saturday, a unanimous decision over Daniel Cormier at UFC 182 in Las Vegas. Jones outworked Cormier, a two-time U.S. Olympic wrestler and previously undefeated MMA fighter, to win the five-round fight decisively.

"With the support of my family, I have entered into a drug treatment facility," Jones said in a statement given through his attorney to Yahoo! Sports. "I want to apologize to my fiancée, my children, as well as my mother, father, and brothers for the mistake that I made. I also want to apologize to the UFC, my coaches, my sponsors and equally important to my fans. I am taking this treatment program very seriously. Therefore, at this time my family and I would appreciate privacy."

The report said Jones passed a follow-up test.

"We support UFC light heavyweight champion Jon Jones' decision to enter a drug treatment facility to address his recent issue," the UFC said in a statement. "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."

"I am proud of Jon Jones for making the decision to enter a drug treatment facility," UFC president Dana White said in a statement. "I'm confident that he'll emerge from this program like the champion he truly is."

Jones last month signed an endorsement deal with Reebok separate from the  athletic apparel's overall deal with the UFC announced in December. Reebok supported Jones on Tuesday.

"We commend Jon for taking the necessary steps to address this issue, and we will support him in any way we can," Reebok said in a statement. "The status of Jon's relationship with Reebok has not changed."

DraftKings, a daily fantasy sports website, recently signed on to sponsor Jones, including offering an opportunity to meet Jones as part of an all-expenses paid trip to Las Vegas for UFC 183 on Jan. 31.

“At this time, DraftKings’ relationship with Jon Jones has not changed, and we commend him for taking the necessary steps to address this issue,” DraftKings co-founder and CMO Paul Liberman said in a statement to Newsday.

It's unclear how the UFC 183 trip prize will be handled.
