The Boston Celtics may be without one of their key players in Saturday's Game 3 matchup against the New York Knicks.

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.

The Boston Celtics are sticking with Al Horford as their starting center for Game 3 of the Eastern Conference semifinals, even though Kristaps Porzingis is available to play.
