Boston Celtics point guard Kyrie Irving was knocked out of Friday's game against the Charlotte Hornets in the first half with a head injury.
The team announced that Irving, who played just two minutes, would not return and was being monitored for a possible concussion.
Irving caught a elbow from Celtics team-mate Aron Baynes.
The Celtics have suffered a number of injuries so far this season. Center Al Horford missed Friday's game with a concussion and Gordon Hayward was lost for the season in the first quarter of the season's first game.
