Cavaliers guard Kyrie Irving broke a bone in his jaw during Friday's game against Milwaukee.
Irving, who only recently returned after missing 11 games with a broken finger, did not travel with the team to New York so he could be fitted with a protective mask that he will wear in Saturday's game against the Knicks.
Irving was injured when he took a hard fall in the first quarter. He was knocked down and hit the side of his face in the foul lane. Irving was in obvious pain but remained in the game. Last season's NBA rookie of the year finished with 26 points in 36 minutes.
This is the latest injury for Irving, who broke his hand this summer. His college career at Duke was limited to 11 games because of a foot injury.
