The Boston Celtics will have to attempt to close out their third consecutive series without their starting center. Kristaps Porzingis was ruled out for Game 4 of the Eastern Conference Finals due to a strained right calf.

The Celtics lead the Indiana Pacers 3-0, which means Boston can afford to play it safe with Porzingis. He's been out since getting injured in Game 4 of the first round against the Miami Heat on April 29.

If Boston closes out Indiana in Game 4, their next game won't be until Game 1 of the NBA Finals on June 6. If the Pacers win, the series shifts back to Boston and Porzingis could play in Game 5 on Wednesday, May 29.
