Beyond All-Stars Jayson Tatum and Jaylen Brown each forgetting to shoot for a half, center Kristaps Porzingis' health has been a major issue in this series against New York. Per Zack Cox of The Boston Herald,

Boston Celtics star Kristaps Porzingis missed the second half of his team's stunning Game 1 loss to the New York Knicks with an illness, and coach Joe Mazzulla told reporters on Tuesday that the big man was day-to-day. Shortly before Game 2 on Wednesday, the team announced that Porzingis would be available.

The Celtics were without Kristaps Porzingis for most of Game 1 as the big man was forced to leave due to an illness.
