NEW YORK (AP) — The Boston Celtics are sticking with Al Horford as their starting center for Game 3 of the Eastern Conference semifinals Saturday, even though Kristaps Porziņģis is available to play.

In a bit of a shocking development, the Boston Celtics lost each of their first two games of their series against the New York Knicks. The reigning champions are down 0-2 as the series heads to New York, and Game 3 is now a must-win for them as they look to avoid a 0-3 series deficit.

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