Chael Sonnen - MMAWEEKLYUFC light heavyweight champ Jon Jones turned heads earlier this week when he took trash-talk a step further by labeling future foe Chael Sonnen as a longtime cheat. Specifically, Jones said Sonnen’s use of testosterone replacement therapy was a result of abusing steroids earlier in his career, adding that relying on such substances was indicative of Sonnen lacking the “heart and attitude of a champion”.

Of course, Sonnen has never actually been linked to steroids though he was suspended a few years ago for an unnaturally high level of testosterone. Still, Jones has realized in retrospect his comments were inappropriate and lacked any real evidence to support his bold claim.

“I had no right to accuse Chael of being a career-long steroid user (and) I apologize,” wrote Jones today on Twitter, joking, “See what had happened was…”

Jones and Sonnen are scheduled to square off in a little more than a week at UFC 159. “Bones” will look to successfully defend his title for the fifth time in the fight, while Sonnen is making a return to 205 pounds after an extended run as a middleweight.
