BOSTON — Before the Boston Celtics took the floor without their biggest star on a night they had to win, Joe Mazzulla implored his players to just pour everything they had into winning one game.
They did, and the defending NBA champions earned another chance to extend their season.
Derrick White had 34 points, including seven 3-pointers, to lead the Celtics to a 127-102 Game 5 win over the New York Knicks on Wednesday night that kept them alive in the Eastern Conference semifinals.
''We did what was necessary to do what we needed to do to get it back to New York,'' Mazzulla said. ''You don't get to pick the test that you have, you pick how you respond to them.''
The Celtics connected on 22 3-pointers to post their first home victory of the series and first without Jayson Tatum following his season-ending Achilles tendon injury.
''Losing JT is tough,'' White said. ''But we've got a lot of guys that are highly competitive, and we didn't want the season to end tonight.''
The Knicks will try again to win the series Friday in New York. If the Celtics win, Game 7 would be in Boston on Monday.
Jaylen Brown added 26 points and 12 assists. Payton Pritchard had 17 points and five 3-pointers. Luke Kornet finished with 10 points, nine rebounds and seven blocks. He started the second half for Kristaps Porzingis, who played just 12 minutes. Mazzulla said Porzingis was having trouble breathing as he continues to deal with a lingering viral illness.
