McGregor, 29, unexpectedly showed up at a UFC 223 media event Thursday at Barclays Center, and was caught on camera throwing a hand dolly through the window of a bus that was carrying UFC fighters.

McGregor was being processed and no charges had been filed as of Thursday night.

UFC lost three fights for its Saturday pay-per-view event directly connected to the incident involving McGregor, the UFC said in a statement late Thursday.

Lightweight Michael Chiesa (14-3) has been pulled from a scheduled bout against Anthony Pettis because of facial lacerations. Flyweight Ray Borg (11-3) has been forced out of a bout against Brandon Moreno because of what the UFC described as multiple corneal abrasions. Both injuries were allegedly caused by McGregor's actions.

And McGregor's own teammate, Artem Lobov (13-14-1), had earlier been pulled from his fight against Alex Caceres because of his participation in the incident. Earlier this week, Lobov was involved in a minor hotel scuffle with UFC lightweight Khabib Nurmagomedov, who is scheduled to fight Saturday against Max Holloway.

"A decision was made by the New York State Athletic Commission to pull me from UFC 223," Chiesa wrote on Twitter. "I'm devastated to say the least. [Pettis], I hope to run this match up ASAP, June 9 in your backyard. That's all I have to say for now. Much love."

UFC president Dana White condemned McGregor's behavior Thursday, calling it "the most disgusting thing that has ever happened" in UFC history. White said credentialed journalists from McGregor's website, The Mac Life, let McGregor and a large entourage into Barclays Center.

In an official statement Thursday evening, the UFC stated, "Lobov has been removed from this weekend's card and individuals involved in the incident are not welcome at tomorrow's ceremonial weigh-in or Saturday's event at Barclays Center."
