Boston Celtics forward Grant Williams underwent surgery on his left hand on Friday, the club said.

The Celtics said that Williams had the surgery to repair a torn radial collateral ligament in the hand. He is expected to be sidelined six to eight weeks before resuming basketball activities.

Williams reportedly injured the hand in March. He continued to play until the Celtics lost to the Miami Heat in the Eastern Conference finals.

Williams, 24, also is slated to become a restricted free agent. He made $4.31 million last season. Boston can match any offer Williams receives on the free-agent front.

Williams averaged career bests of 8.1 points and 4.6 rebounds in 79 games (23 starts) this season. He has career marks of 6.2 points and 3.4 rebounds in 288 games (58 starts) over four NBA seasons.
