With just over seven minutes to go in the ball game, and the Celtics trailing by two, Al Horford threw an ill-advised pass to Neemias Queta that resulted in a fast break for Philadelphia.
It was an uncharacteristically poor decision for the veteran, who often serves as the most calming yet energizing presence on the roster.
So, he made sure to make up for it.
Horford sprinted back on defense, denied Tobias Harris at the rim, and then teamed up with Jaylen Brown to block him once again.
Back-to-back fourth quarter blocks for 25-year-old Al Horford.
