NEW YORK — The Celtics could be at full strength when they play the Knicks for Game 4 of the East semifinals. Sam Hauser was upgraded on the injury report to questionable with his right ankle sprain. Nobody else is listed on the injury report otherwise for the C’s as they’re looking to even the series against the Knicks.

Payton Pritchard led the charge with 23 points off the bench, including five three-pointers, while Jayson Tatum contributed 22 points, nine rebounds, and seven assists. Jaylen Brown and Derrick White also added 19 and 17 points, respectively.

The Celtics drained six of their first seven 3-pointers in Saturday and continued to bolster their confidence by making hustle plays that earned them extra opportunities to launch more threes.
