Cormier '100 percent' positive Jones took steroids for 1st bout

Daniel Cormier is not backing down from his claim that Jon Jones has broken the rules for much of his career.

In an interview with Ariel Helwani, the current light heavyweight champ was adamant that "Bones" has frequently used illegal substances throughout his career - including the first time the two fought at UFC 182.

"I do, 100 percent," Cormier responded when asked if he believed Jones was using something illegal in 2015, according to Bloody Elbow's Milan Ordonez. "Physically, there were some differences, but also, logically, there were differences. Medically, there were differences. There were a lot of reasons as to why it'd point to him doing stuff like that.

"If he's gonna do things to sabotage himself, why wouldn't he do things to enhance himself? He tested positive for those two (substances), his brother tested positive for the same two things, the same exact time. There are just so many reasons to believe that he had been cheating."

Jones tested positive for hydroxy-clomiphene and Letrozole ahead of UFC 200, though the USADA made it clear he was not suspended for performance-enhancing drugs.
