UFC superstar Conor McGregor made a brief appearance in a NYC courtroom Thursday for his first hearing in the April melee outside Brooklyn’s Barclays Center that left several injured after he threw a hand truck at a bus carrying a group of fighters.

The 29-year-old was hit with multiple charges for the April 5 incident, including two for misdemeanor assault and one for felony criminal mischief .

“I regret my actions that led to today,” McGregor told a gaggle of reporters outside the courthouse after the hearing, via TMZ.. “I understand the seriousness of this matter and I am hopeful this will get worked out.”

Inside the courtroom, McGregor’s attorneys and the Brooklyn District Attorney’s Office told the judge that a plea deal is under negotiation. His next court date is reportedly scheduled for July 26. McGregor and co-defendant Cian Cowley remain free on bail.

Fighters Michael Chiesa and RayBorg both suffered injuries that led to the cancellation of their scheduled UFC 223 bouts on April 7 when McGregor and several members of his entourage stormed a Barclays Center loading dock and threw chairs and a hand truck at a bus filled with UFC athletes.

McGregor has not fought a UFC bout since November of 2016, which led to the forfeiture of his lightweight title. If convicted on all counts, the Dublin, Ireland native faces up to seven years in prison.
