McGregor had called Nurmagomedov, who does not drink alcohol because of his Muslim faith, "backwards" because he would not share his Proper Twelve whiskey with him, had branded his father a "quivering coward" and spoke negatively about Dagestan, Khabib's homeland.
After finishing off McGregor with a fourth-round choke, Nurmagomedov pointed at the Irishman's corner, threw his mouthpiece in that direction, then leaped over the cage to go after Dillon Danis, a brash Bellator fighter who serves as McGregor's jiu-jitsu coach.
"We lost the match but won the battle", McGregor wrote.
McGregor also said that "the war goes on" as he seemingly ramps up his campaign to book a rematch bout with Nurmagomedov.
UFC chief Dana White confirmed later that three of Nurmagomedov's team were arrested and taken to jail but were released later because McGregor refused to press charges.
Interpol says missing president has resigned after wife reveals ominous message
Interpol said the senior vice president of its executive committee, Kim Jong Yang of South Korea, would become acting president. Earlier Interpol had indicated Meng's disappearance was "for the relevant authorities in France and China" to deal with.
Early Sunday morning, McGregor was already thinking of a rematch. Shortly after Khabib incited his brawl, two men presumably involved with Khabib entered the Octagon and attacked McGregor, sparking a second melee.
The most pressing issue for "The Eagle" is how heavily he is sanctioned for the carnage that unfolded at the T-Mobile Arena on Saturday night.
UFC president Dana White revealed it wasn't him or the company the Khabib had to worry about when it came to discipline but the Nevada Athletic Commission saying, "The Nevada State Athletic Commission is going to go after him pretty hard". "I want to change the game, you can not talk about religion, about nationality".
"You know me, I'm always mad at everything". But I don't understand how people can talk about how I jump on the cage. McGregor's signature pre-fight trash-talk gab took on a more insidious nature, which clearly got to Nurmagomedov and exploded into violent chaos after the fight was supposed to be over. When you have such an incredible event that we've worked hard to build over the last several months and it goes ideal, I mean literally it was too eerie.
