The Boston Celtics are sticking with Al Horford as their starting center for Game 3 of the Eastern Conference semifinals Saturday, even though Kristaps Porzingis is available to play. Porzingis has been fighting an illness and was limited in the Celtics' two losses to the New York Knicks in Boston.

Boston Celtics veteran big man Al Horford said the team was impacted by the loss of Kristaps Porzingis in Game 1 against Knicks.

Kristaps Porzingis said after Game 2 that he's feeling off due to an illness as that's another challenge the Celtics must overcome.
