Jon Jones Says He's 'Leaving Doors Open' for Comeback

Jon Jones says he will "more than likely" never fight again, but confirmed he remains in the UFC's drug-testing pool and is "leaving doors open" for a potential return.

The former UFC heavyweight and light heavyweight champion made the comments Friday night on Twitter, responding to a fan who asked if he intends to compete again. "More than likely, I won't fight again, but as of right now I'm still getting drug tested," Jones wrote. "Leaving doors open, you never know what the future holds." Per the UFC's official drug-testing website, Jones has been tested four times in 2026.

What Jon Jones Has Said About Retirement

Jon Jones retired in June 2025 after his heavyweight title defense against Stipe Miocic at UFC 309, a result that spoiled a long-rumored unification bout with interim champion Tom Aspinall. He later signaled interest in fighting again once UFC CEO Dana White and President Donald Trump announced a UFC event at the White House, though Jones ultimately was not booked for that card. Friday's comments mark the latest flip in a pattern that has defined the tail end of his career: step away, hint at a return, then let the idea sit without a firm commitment.

Jones is regarded as one of the greatest fighters in MMA history. He won the UFC light heavyweight title at 23, the youngest champion in promotional history, and defended it 11 times between 2011 and 2020. He added a heavyweight title in 2023 by submitting Ciryl Gane for the belt vacated by Francis Ngannou, then beat Miocic in what remains his last fight.

Why Staying in the Testing Pool Matters

Jon Jones remaining in the UFC's drug-testing pool is the clearest practical signal that a comeback has not been ruled out. Fighters who are truly finished typically exit the pool, since staying in it requires ongoing random testing with no immediate fight on the books. Jones being tested four times already in 2026 suggests he wants to preserve the option of taking a fight on short notice without having to rebuild a testing history first, a detail that matters to the UFC and to any opponent across the table from him.

For bettors, that detail is more meaningful than the social media back-and-forth. Jones has no scheduled opponent and no date, so there's nothing to price yet. But his continued presence in the testing pool keeps him in the conversation around the heavyweight title picture, where Tom Aspinall sits as champion. Any market move tied to Jones won't happen until a bout agreement is real, and his history of reversing course on retirement means oddsmakers and sportsbooks are likely to treat a Jones booking as unconfirmed until contracts are signed.

Jones also used the week to keep needling Colby Covington, who had called him a "terrible human being" over his mentorship of heavyweight prospect Gable Steveson. Jones fired back on Twitter, saying, "I just like reminding Colby that I'm not the man I used to be. And even at my weakest, I've always been better than him. I'm everything he could never be, and I know it kills him inside. You can see it in the passion he has when it comes to me. I just want to give him a little more to hate. That's all."
