Jon Jones is one of the most talented fighters of all time, arguably the number one pound-for-pound fighter on the planet - but he really is his own worst enemy.
Just when it looked like the 28-year-old was on the right track and was on the road to redemption after a disastrous 2015, Jones had tailed back down shit creek.
Due to contest the main event at the UFC's showcase event last Saturday night, Jones was pulled from UFC 200 less that 72 hours prior to the fight after testing positive for a banned substance - the failed out of competition test stems back to mid-June.
Jones got emotional in a press conference addressing the situation, and insisted he knowingly took nothing. Despite his troubled past, and actions outside of the cage - the reigning light heavyweight champion has never failed a drug test.
Speaking to Ariel Helwani on the MMA hour, Jones' manager Malki Kawa gave an update on the situation, and reiterated the points Jones made in his press conference. While he wouldn't disclose what any more information about which substances he tested positive for - he insisted Jones never took anything knowingly.
It's not that we're trying to hide anything, we're not trying to get ahead of it and tell people what it is. I'm going to stand by our comments at the press conference. Jon at no point in time is a cheater, has ever cheated. (He) has never taken any substance that you know, he knowingly knew of that was on the banned list.
I know for a fact that Jon isn't a cheater and I know for a fact that Jon didn't take anything knowingly
I'm going to stand by until the day that I die. I don't care how this turns out. You know what I mean?
That's just one thing about this guy, he is not a cheater.
Jones' B-sample test showed the same result as the original test, flagging Jones for two separate banned substance. He will be given a full hearing before any sanction is imposed - but he potentially faces a 2-year ban from the sport.
Currently on probation for a hit and run incident 12 months ago that saw him suspended by the UFC and stripped of his light heavyweight title - the failed drug test didn't violate his probation, according to TMZ
