Kristaps Porzingis joined the starting lineup for the first time in Game 1 against the Knicks, but it was a short-lived stint.

ESPN NBA Insider Shams Charania said on ABC’s coverage before Knicks-Celtics Game 3 on Saturday that Porzingis is still dealing with the effects of a virus that had ailed him back in March. Charania said the Celtics star thought he had felt he improved, but things have been up-and-down since the second round began this week.
