Conor McGregor may get away with punches, but not when he’s outside the cage.

The MMA fighter has been charged with assault for punching a man in a Dublin bar in April, ESPN reported. McGregor was served with a summons and is due in court on Oct. 11.

McGregor’s assault charge comes with a maximum of six months in prison if he is convicted, a fine of $1,646 or both, according to The Independent. The 31-year-old previously expressed regret over the incident, which allegedly stemmed from an older customer at the bar turning down McGregor’s brand of whiskey.

“I was in the wrong,” McGregor told ESPN in August. “I must come here before you and take accountability and take responsibility. I owe it to the people that have been supporting me.”
