Mixed martial arts star Conor McGregor is due in court in New York for a hearing on charges stemming from a backstage melee that was caught on video.
He is expected to be joined in Brooklyn by friend and co-defendant Cian Cowley.
Video showed what appeared to be McGregor hurling a trolley at a bus full of fighters after a news conference for the UFC 223 event at Barclays Centre in April.
Two fighters hurt by broken glass were unable to compete.
Prosecutors would not say if they expected a resolution.
Cowley and McGregor have been free on bond. They took a private jet together from Ireland for the hearing.
