While Porzingis is active and available for Joe Mazzulla's Celtics squad, the team will be starting Kornet in his place for Game 6. "Luke Kornet starting for Kristaps Porzingis," The Athletic's Fred Katz shared on X.

Kristaps Porzingis wasn't himself down the stretch of the postseason. Really, the 7-foot-3 Latvian wasn't himself off the court for the Boston Celtics, either, as the New York Knicks sent them home. The mysterious Porzingis illness is going to get some more testing going forward after already getting some done.

The Celtics are making a big change in the starting lineup for Game 6 against the Knicks with the season on the line.
