The St. Louis native went down late in the game with a non-contact injury that had him writing on the ground in pain.

The Celtics blew a 14-point lead, then lost their best player to injury in a Game 4 loss to the Knicks that pushed Boston to the brink of elimination.

Not only did the Boston Celtics lose to the New York Knicks Monday to fall to within one game of elimination from the NBA playoffs, they also lost Jayson Tatum to a lower-leg injury. Which means he may not be around to help them fight back from the 3-1 series deficit.
