Conor McGregor appeared in court on Friday over an alleged assault on a man in a Dublin pub in April.
The incident occurred April 6 at the Marble Arch pub. McGregor was captured on camera punching a man, who was sitting at the bar, in the face. The man is in his 50s.
In an August interview with ESPN, McGregor expressed remorse for his "unacceptable behavior" in the situation.
The 31-year-old Irish fighter stood at the back of the Dublin courtroom as his solicitor, Michael Staines, asked for the case to be adjourned until Nov. 1 pending the disclosure of evidence.
Judge Marie Keane asked the twice Ultimate Fighting Championship title-holder, dressed in a navy pattern suit, to appear again in three weeks' time when he would be asked to enter a plea or seek a date for the case to be heard.
McGregor was charged in a separate case in April 2018 with three counts of assault and one count of criminal mischief after police said he attacked a charter bus in New York carrying UFC fighters.
He pleaded guilty to a reduced disorderly conduct charge in that case.
