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.

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

Boston Celtics star Kristaps Porzingis missed the second half of his team's stunning Game 1 loss to the New York Knicks with an illness, and coach Joe Mazzulla told reporters on Tuesday that the big man was day-to-day. Shortly before Game 2 on Wednesday, the team announced that Porzingis would be available.
