The Celtics again collapse late in Game 4 against the Knicks — but Jayson Tatum’s uncertain lower leg injury overshadows the game’s outcome.

To make matters worse, the Celtics lost Jayson Tatum to a troubling non-contact injury late in the game. The six-time All-Star was seen writhing in pain on the floor after sustaining an injury to his right leg. Tatum had to be helped to the locker room and was unable to return to what was a close game at that point.

The Celtics didn't satisfy the fans shouting to "Stop shooting so many 3-pointers!" They just made them this time. Will they be better on nights when they don't shoot well?

The Celtics collapsed yet again, falling into an 0-2 hole and an identity crisis that will decide whether their title defense ends early.
