UFC star Conor McGregor has pleaded guilty to disorderly conduct over a backstage brawl in New York in April.
The Irish mixed martial artist will attend an anger management programme, serve five days of community service and pay for the damage he caused.
He will avoid prison as a result of his agreement to plead guilty.
McGregor, 30, was charged with assault, criminal mischief and other crimes for his role in the altercation.
Video footage appeared to show McGregor and his entourage in an underground car park smashing windows on a bus filled with UFC fighters who were at the Barclays Centre Arena in Brooklyn to publicise the upcoming UFC 223 event.
One fighter on the bus was hit and cut by an object thrown through a window, while another had the cornea of his eye cut by the glass as it broke into dust.
McGregor handed himself in to police soon after the incident.
Outside the courthouse, McGregor thanked prosecutors and the judge for letting him “move forward.”
“I’d like to say to my friends, my family and my fans: Thank you for your support.”
A small crowd of fans cheered as he headed for his car.
He pleaded guilty to disorderly conduct, a violation which will not result in a criminal record.
The plea will have no effect on his immigration status or his ability to fight, according to his defence lawyer Bruce Maffeo.
At the time of the brawl, McGregor was angry that the UFC had stripped him of the lightweight title, according his Twitter posts.
The UFC took away the title after McGregor decided not to defend it in favour of taking a highly lucrative boxing match against the undefeated Floyd Mayweather – which Mayweather won by TKO in the 10th round.
