Jon Jones' B sample confirms positive test result

The UFC fighter will not fight in UFC 200 and his future in the sport now hangs in the balance

Jon Jones' B sample tests have confirmed the presence of a banned substance, according to the United States Anti-Doping Agency.

The UFC fighter, who was set to face Daniel Cormier at UFC 200 on Saturday night, has put himself in a precarious situation having recently returned to the ring following an indefinite suspension based on a hit-and-run incident involving the man who many believe the is the best pound for pound fighter in the world.

"The B sample that was requested has confirmed the findings of the A sample," Ryan Madden, the spokesperson for the USADA said.

"They found something in one of my samples," Jones said Thursday. "I don't even know how to pronounce it. I've been taking the same supplements the majority of my career. I've been so outspoken about being against any type of performance enhancers. To this day, I'm extremely against performance enhancers.

"The whole thing sucks. Being labeled as someone who would cheat hurts more than anything else I've ever been through in my career."

Jones faces a suspension of up to two years for the failed drug test but says he will be back regardless of how long it takes. Given the fact that he is almost 29 and would be 31 when his suspension finished, there is concern over whether we have seen the peak of Jones' career taken away through suspensions for varying reasons.
