Jones, flanked by PR representative Denise White and manager Malki Kawa, faced the media at the MGM Grand for the first time following his removal from the UFC 200 fight card.

Neither Jones nor Kawa specified the substance he had tested positive for, but the suggestion was that he had taken a tainted supplement.

Jones explained that he was completely unaware of anything that could have triggered the positive test, saying: “There’s a few things that have nothing to do with performance that I’ve tried. Right now, I’m trying to think of everything I’ve taken.”

And the interim champion apologised to rival Cormier, explaining: “I want to apologise to Daniel Cormier. I know this fight means a lot to him. And it means a lot to me.”
