The Celtics insist they know what's wrong with Kristaps Porzingis, but they won't give away any details. Boston Celtics center Kristaps Porzingis has been dealing with an illness that knocked him out of the lineup in March and has forced him to miss time here and there ever since.

Kristaps Porzingis has been limited in the East semifinals due to an illness, though there's still a lot unknown about it.

Porzingis has been pretty limited during the 2025 NBA Playoffs due to an illness, particularly in the second round against the New York Knicks. In Game 1, he started and played 13 minutes but exited the game at halftime. In Game 2, he came off the bench but only played 14 minutes. Boston lost both games.
