Boston led 51-49 at the half, with Embiid carrying Philadelphia with 22 points and 10 rebounds.

The Celtics were able to stay close despite Tatum picking up his third foul near the end of the first quarter and having to sit the entire second quarter. Tatum entered the game averaging 32.5 points on 10-of-17 shooting from 3-point range in the series.

Midway through the third, Walker completed a personal 8-0 run with a fast-break layup and foul on Embiid — his fourth. But Philadelphia didn't fold with its All-Star center on the bench, instead battling back to tie it.
