Khabib Nurmagomedov has threatened to quit UFC in a stunning outburst aimed directly at the sport’s governing body.

Nurmagomedov retained his UFC lightweight belt on Saturday by forcing a fourth-round submission by challenger Conor McGregor.

But the undefeated Russian marred his convincing victory by jumping out of the cage immediately afterwards to confront McGregor’s support team and spark a mass brawl.

The Nevada State Athletic Commission has withheld Nurmagomedov’s two million dollar fight purse during its investigation.

UFC president Dana White has hinted at banning Nurmagomedov’s teammate, fellow Russian and UFC fighter Zubaira Tukhugov, for his part in the incident.

“Why do you have to punish my team, when both teams fought,” Nurmagomedov said in a statement posted on his Instagram account.

“If you say that I started it, then I do not agree, I finished what he had started.

“In any case, punish me, @zubairatukhugov has nothing to do with that.If you think that I’ll keep silent then you are mistaken. You cancelled Zubaira’s fight and you want to dismiss him just because he hit Conor.

“But don’t forget that it was Conor who had hit my another Brother FIRST, just check the video.

“If you decide to fire him, you should know that you’ll lose me too. We never give up on our brothers in Russia and I will go to the end for my Brother.

“If you still decide to fire him, don’t forget to send me my broken contract, otherwise I’ll break it myself.

“And one more thing, you can keep my money that you are withholding. You are pretty busy with that, I hope it won’t get stuck in your throat. We have defended our honor and this is the most important thing. We intend to go to the end.”

It's safe to say plenty have reacted to Khabib's statement, including the likes of Ricky Hatton, Paulie Malignaggi, Daniel Cormier, and now UFC legend Chuck Liddell has got involved.

He posted on his own Instagram account reacting to the Russian's statement, and it's safe to say he has full respect for the champ.
