However, Nurmagomedov then jumped outside the Octagon and attacked McGregor's friend and training partner, Dillon Danis.
"The Nevada Athletic Commission pulled footage from us and there's an investigation going on", UFC President Dana White said at a post-fight press conference, as transcribed by SB Nation's Bloody Elbow blog.
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.
One Irish fan is knocked out and left with blood streaming from his face during the disturbing incident.
On Twitter, he said: "We lost the match but won the battle".
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.
I want apologize to the Nevada [State] Athletic Commission, the governor of Nevada and I want to thank the Las Vegas police department and security for doing such an unbelievable job.
"I don't know when things started turning into some kind of s- show?"
"And I mean Khabib".
White also said of the three Nurmagomedov associates: "The guys who jumped in will never fight here". Even if you were the biggest Conor fan ever, you would at least have to respect him.
While it would be a tantalizing - and lucrative - prospect, Khabib v McGregor 2 seems like a distant prospect at the moment.
Former UFC interim champ Tony Ferguson saw off Anthony Pettis in his return to action in the co-main event on Saturday, with the pair serving up a brutal slugfest that saw "El Cucuy" win via second-round TKO. When you have such an unbelievable event that we've worked hard to build over the last several months and it goes flawless, I mean literally it was too eerie.
