Breaking: Jon Jones tests positive for cocaine, enters drug rehab following UFC 182 win over Daniel Cormier

We finally found the one fighter who poses a legitimate threat to Ultimate Fighting Championship (UFC) light heavyweight champion Jon Jones.

Jon Jones.

"Bones" tested positive for benzoylecgonine, a cocaine metabolite, in a random drug test administered by the Nevada State Athletic Commission (NSAC) back on Dec. 4, 2014.

Since the NSAC follows the World Anti-Doping Agency (WADA) policies and benzoylecgonine is not on the out-of-competition banned substance list, a punishment could not be levied against Jones and he was permitted to compete.

Jones passed a second test prior to his UFC 182 victory over Daniel Cormier last Saturday night (Jan. 3, 2015) at MGM Grand in Las Vegas, Nevada, and has since entered a drug rehabilitation facility.

Yahoo! Sports initially reported the news and has the champ's statement:

"With the support of my family, I have entered into a drug treatment facility. 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 NSAC chairman, Francisco Aguilar, said he is "pleased that Mr. Jones is addressing this issue and seeking help for his problem."

The UFC has released the following statement via UFC.com on the matter:

"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."

After defeating the previously unbeaten Cormier at UFC 182 to begin the new year -- in which he said he would prove he is the best ever -- this is undoubtedly a huge setback for the light heavyweight champion, especially after working so hard to erase the memory of his run-in with the law back in 2012.
