Tatum delivered an exceptional performance, scoring 42 points, including seven three-pointers. However, with under three minutes remaining in the fourth quarter, Tatum suffered a non-contact injury to his right leg while attempting to recover a loose ball.

Al Horford has his mind on Jayson Tatum after seeing the injury his teammate suffered during the Boston Celtics’ Game 4 loss to the New York Knicks on Monday night. The injury happened within the last six minutes of the fourth quarter.

It was the latest on a growing list of Celtics ailments — Brown, Porzingis, Jrue Holiday and Sam Hauser all have been sidelined or limited this postseason, and Tatum missed a first-round game with a bone bruise in his wrist — and by far the most damaging, barring a surprisingly favorable MRI result.
