The Boston Celtics will be missing some size on their bench for Monday night's game vs. the Cleveland Cavaliers.

Robert Williams has been ruled out with left hip soreness, the team announced Sunday. Rookie Romeo Langford was also ruled out as he continues to recover from the ankle injury he suffered during a game with the Maine Red Claws.

On the bright side for Boston, Gordon Hayward could make his long-awaited return to the court after missing the last month with a fractured left hand.

Hayward originally was slated to return from his injury around Christmas.

The Celtics (16-5) and Cavaliers (5-17) will face off at 7:30 p.m. ET on Monday.
