UFC president Dana White has slammed the "disgusting" scenes which have overshadowed UFC 223 in New York.
Conor McGregor turned himself into the New York Police Department on Thursday night after video footage allegedly showed the Irish fighter and his entourage storming the Barclays Center and damaging a bus window at the UFC 223 media day.
White condemned the behaviour McGregor, who was stripped of his UFC lightweight title ahead of the incident on Thursday, and believes the Irishman is now going to be "sued beyond belief".
"This is the most disgusting thing that has ever happened in the history of the company, and there is a warrant out for Conor McGregor's arrest," White told reporters after the incident.
"And they're looking for him right now. His plane cannot take off, he cannot leave the state of New York with this warrant.
"He'll be grounded, and I'm assuming eventually if they don't catch him, he'll turn himself in. You can imagine he's going to be sued beyond belief and this was a real bad career move for him."
NYPD confirmed one person had been injured as the bus window was smashed, with the chaotic scenes leading to three fights being cancelled this weekend.
Michael Chiesa, who received "several facial cuts", tweeted to say the New York State Athletic Commission had decided to pull him from his bout against Anthony Pettis.
Addressing his opponent, he said: "I'm devastated to say the least. @Showtimepettis I hope to run this match up ASAP, June 9th in your backyard. That's all I have to say for now. Much love."
UFC also released a statement, confirming Chiesa's injuries, and said flyweight Ray Borg would not be taking part in his fight against Brandon Moreno due to "multiple cornea abrasions".
"Lightweight Michael Chiesa, who received several facial cuts, was deemed unfit to fight by the New York State Athletic Commission and the UFC medical team, and he was removed from his bout against Anthony Pettis," it said.
"Flyweight Ray Borg, who was scheduled to face Brandon Moreno, was deemed unfit to fight as well due to multiple cornea abrasions."
