Gordon Hayward will undergo surgery on his fractured left hand in New York on Monday afternoon, and a timeline when he returns to the Boston Celtics will follow the procedure, his agent, Mark Bartelstein of Priority Sports, told ESPN's Adrian Wojnarowski.
Hayward suffered the injury in Saturday's win with 135-115 over the San Antonio Spurs.
The injury happened when he collided with Spurs forward LaMarcus Aldridge, who was trying to set a screen behind Hayward not seeing him coming. Aldridge was called an offensive foul at the game, and Hayward, whose left arm was caught between his body and Aldridge, immediately began to shake his hand and went straight to Boston's locker room.
Hayward is averaging 18.9 points, 7.1 rebounds and 4.1 assists in eight games this season while shooting 55.5% overall and 43.3% from 3-point range.
His play has translated into fantastic reviews from scouts who have seen Hayward early this season, as he was clearly favored by a full off season dedicated solely to working with his body and games. After missing all but six minutes of his first season with the Celtics after suffering horrific leg and ankle injuries in the opening game of the 2017-18 season against the Cleveland Cavaliers, Hayward occasionally looked casual during last season.
