UFC light heavyweight champion Jon Jones has confirmed on social media he is relinquishing his title.
'Bones' has been caught up in an online stoush with his boss, UFC president Dana White, with the two sparring over Jones' value.
The talented, but flawed American, has been campaigning for an interim heavyweight title fight against Cameroon's Francis Ngannou, but talks fell flat when Jones and the UFC disagreed on his worth.
In recent days, Jones has accused White of being a "liar" and threatening to walk out on the company to pursue a boxing career.
On Monday, he apparently gave up his title.
"To the light-heavyweight title -- veni, vidi, vici," tweeted Jones, using the Latin phrase of "I came, I saw, I conquered," attributed to Julius Caesar.
Asked if he was giving up his title, he tweeted "Yes."
White said Jones was after "crazy" money for a potential blockbuster fight against Ngannou, citing demands of $US30million.
Speaking on Sunday, White appeared as though he was washing his hands of the troubled superstar fighter.
"He can do whatever he wants to do. He can sit out, he can fight, he can whatever," White said.
"Jon Jones can say whatever he wants publicly. It’s his God-given right here in America. He can say whatever he wants. And when he’s ready to come back and fight, he can."
Jones tweeted "goodbye for now" to his fans, before appearing to signal he would return in 2021 for a fight with UFC middleweight champion, New Zealand's Israel Adesanya.
"[Dominik] Reyes vs Jan [Blachowicz] For the UFC light heavyweight championship of the world. As of right now, I got nothing to really gain fighting either of them," Jones wrote.
"Let me know if you guys want to set up a day in 2021 for that Izzy fight. Hopefully you guys will be willing to pay by then."
Recently, Adesanya told Newshub he expected Jones would find a way out of fighting Ngannou and said his talk of a move to heavyweight was just hype.
"I will tell you this with absolute certainty. Jon Jones will not take that fight - he will find an excuse or a way out," Adesanya said.
"This is just for hype and a few social media likes.
"This mother f****r expects me to move up in weight to fight him and I will.
"Let me just clean out my division and then I'll f*** him up.
"Look. he's been at 205 [light heavyweight] for 10 years and been talking about jumping up that whole time - but has he ever moved up one? No he hasn't, because he's a pussy.
"He talks a whole bunch of shit - he ain't doing it. No one wants that Francis Ngannou smoke - no one."
