Nurmagomedov jumped out of the cage before leaping feet first at McGregor's team mate and cornerman Dillon Danis, and three of the Russian's team were arrested and later released on a black night for a sport that has struggled to win mainstream acceptance for 25 years.
Meanwhile, two men entered the cage and sucker-punched McGregor, who defended himself before security personnel separated everyone.
The victorious Khabib leapt over the fence and attacked Dillion Danis after the sanctioned fight, while McGregor fought off some of Khabib's teammates having just nearly been chocked out.
"They looked at the footage and felt there was no need to hold his".
"I slapped him as promised". He was supposed to fight McGregor teammate Artem Lobov later this month, but UFC President Dana White yanked him from that fight and kicked him out of the promotion after Saturday night's melee in Las Vegas.
McGregor's US$3m purse was not withheld after commission officials examined video footage and determined his side had done nothing wrong. Conor refused to press charges. The Nevada State Athletic Commission is going to go after him, I'm sure, pretty hard.
Nurmagomedov showed up at the postfight news conference around midnight local time. "This is not my best side", he said.
He went on to complain bitterly about McGregor's behaviour in the lead-up to the fight that exacerbated the bad blood between the two teams. He talk about my religion, he talk about my country, he talk about my father.
However, it proved to be too little, too late, and Nurmagomedov was once again on top in the fourth, sapping McGregor's energy with his excruciating pressure before the choke ended the fight 3:03 into the fourth round. After McGregor tapped, referee Herb Dean had to restrain Nurmagomedov and push him away from McGregor. "There's gonna be an investigation by the Nevada State Athletic Commission, and. there's gonna be big-money fines, and these guys are in big trouble".
