Conor McGregor is apparently a step or two beyond livid at the prospect of having his lightweight title forfeited.

UFC president Dana White announced at a UFC 223 press conference Wednesday that McGregor’s title would go to the winner of Saturday’s bout between Max Holloway and Khabib Nurmagomedov. Never one to shy away from controversy, McGregor showed up at the Barclay’s Center Thursday, but with no intention of talking things through. According to Yahoo Sports, McGregor, along with about 30 of his crew, got into an altercation with a few fighters at the UFC 223 media event.

Witnesses said McGregor was shouting at a transport van carrying fighters that were leaving media day, including Nurmagomedov and his team, demanding that they get out. He then began hurling guardrails and chairs at the vehicle. Michael Chiesa, who is scheduled to fight Anthony Pettis Saturday night, suffered a laceration to his forehead, and another UFC employee suffered a broken knuckle. McGregor reportedly fled the scene before police arrived. The NYPD confirmed they’re investigating the incident.

White said a confrontation between McGregor’s teammate, Artem Lobov, and Nurmagomedov touched off the melee. As a result, White said, Lobov won’t be allowed to fight Saturday. He was scheduled to meet Alex Caceres at the pay-per-view event.

White told reporters he was disgusted by McGregor’s actions.

“This is the most disgusting thing that has ever happened in the history of the company,” he said. “You don’t like Khabib, and you don’t like what happened, then fight Khabib. You can come in here and do it legally…But you want to grab 30 friends and do what you did today? It’s disgusting.”
