Per the Boston Herald:
Kristaps Porzingis will miss the Celtics’ In-Season Tournament quarterfinal game against the Pacers in Indiana as he continues to nurse his left calf injury, the team announced.
Porzingis initially suffered the ankle injury on Nov. 24 in the Celtics’ loss to the Magic, when he left the game in the third quarter and didn’t return. Celtics coach Joe Mazzulla said last Monday that he would be re-evaluated in a week.
