Both the New York Knicks and Boston Celtics may be without one of their key players in Monday's Game 4 matchup.

Hauser suffered an ankle sprain in the Celtics’ Game 1 loss last week against the Knicks after he landed awkwardly following a 3-point contest of OG Anunoby. He took part in Boston’s shoot around Monday morning before Game 4, going through a full workout with Boston coaches.

Boston Celtics forward Jayson Tatum left Monday's Game 3 against the New York Knicks in the fourth quarter with what appeared to be a foot or ankle injury. He was assisted off the court by trainers and taken through the Madison Square Garden tables in a wheelchair.
