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.

If the Celtics are to avoid the dreaded 0-3 series deficit from which no team has ever escaped, they'll need to play better in the secnd half.
