MIAMI (AP) — Boston center Kristaps Porzingis left the Celtics’ playoff game in Miami on Monday night late in the first half with what the team said was right calf tightness.

The play happened with about 2:35 left in the second quarter. Porzingis took a dribble as he tried to move to his left, then pulled up — without any visible contact on that play — and immediately motioned to the Boston bench. He was subbed out eight seconds later and went directly to the Celtics’ locker room, stopping along the way to pull the top of his jersey over his face.

The Celtics went on to win 104-88, taking a 3-1 lead in the Eastern Conference first-round series over the Heat.

“I thought everybody just stepped it up,” Celtics coach Joe Mazzulla said.

Mazzulla said he did not have any updates on Porzingis’ condition. ESPN reported that Porzingis would get imaging on Tuesday, which would be a logical step after such an injury.
