The Celtics lost small forward Gordon Hayward to a broken left hand in their game vs. the Spurs on Saturday.
Hayward was injured late in the first half in San Antonio. He collided with Spurs big man LaMarcus Aldridge while trying to guard a driving Dejounte Murray.
Hayward's agent, Mark Bartelstein, told ESPN's Adrian Wojnarowski that Hayward will be examined by a specialist on Monday. If surgery is needed, Bartelstein added, it will be peformed the same day.
Hayward, 29, came into the night averaging 20.9 points, 7.9 rebounds and 4.6 assists in his first seven games this season.
This is Hayward's second major injury in a two-year span. He dislocated his left ankle and fractured his left tibia early in his Celtics debut in 2017. Hayward had joined the Celtics as a free agent that summer after playing the first seven years of his career with the Jazz.
