Boston, however, will be hoping to receive some reinforcements. Forward Sam Hauser left the game with an ankle injury and did not return. Kristaps Porzingis, one of their most important role players, was able to muster 13 minutes of action before also leaving the game with an illness.

The Celtics led the New York Knicks by as much as 20 points in the third quarter, but the Knicks then began a furious comeback and won the game in overtime. After Boston took that 20-point lead, the Knicks outscored them 56-33 to end up tying the game and force overtime.

On Tuesday, less than 24 hours after the Game 1 loss, Mazzulla gave a positive update on both Porzingis and Hauser, commenting that they will be listed as day-to-day. The third-year coach also added that the Latvian center "felt a little better today," per The Athletic's Jay King.
