The riot began when four members of Khabib's team jumped into the cage and reportedly began to attack Conor.
On the same night, Conor McGregor tapped out to Khabib Nurmagomedov in the main event as the Russian retained his Lightweight title. Despite being under the scrutiny of the athletic commission, there was no word yet if Nurmagomedov might face legal charges for going outside of the Octagon and attacking McGregor teammate Dillon Danis.
McGregor has been accused of crossing lines in his attempts to hype the fight, which is expected to smash the previous pay-per-view buyrate record when official figures are released.
The commission's first move was to hold Nurmagomedov's guaranteed US$2 million purse indefinitely, and it's unclear whether law enforcement will pursue charges. Nurmagomedov said after apologising to the Nevada commission during a brief post-fight statement to reporters, his title belt displayed on the dais before him. You can not talk about religion or nations. "I don't know what to say right now, I'm disgusted".
And now, Conor's mother Margaret, who was also present at the fight has shared a heartfelt message following her son's defeat and UFC brawl.
UFC president Dana White implemented a later start time when Michael Bisping fought in Manchester, delaying the fight to 3am.
Margaret also turned off comments on her Instagram post following the antics of Saturday night.
McGregor crowed when Abdulmanap Nurmagomedov, the champion's beloved father and a longtime wrestling coach, couldn't attend UFC 229 because he couldn't secure a USA visa in time.
"The fans got an incredible fight and a great show".
