The Boston Celtics may be without one of their key players in Saturday's Game 3 matchup against the New York Knicks.

The New York Knicks defeated the Boston Celtics 121-113 in Game 4. A 39-point game from Jalen Brunson and 23 from Karl-Anthony Towns and Mikal Bridges gave them a commanding 3-1 series lead.
