Kristaps Porzingis said after Game 2 that he's feeling off due to an illness as that's another challenge the Celtics must overcome.

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.
