New York looks to finish out series against Boston in Game 5

Jayson Tatum carried off floor with right leg injury and Celtics star will have MRI

CRUMPLED: Boston talisman Jayson Tatum feels the pain in the closing stages of Monday's Game Four of the Eastern Conference NBA playoffs at Madison Square Garden in New York. 

Jalen Brunson had 39 points and 12 assists, and the New York Knicks moved a win away from their first Eastern Conference finals appearance in 25 years and pushed the defending champion Boston Celtics to the brink of elimination with a 121-113 victory in Game 4.

The Celtics will have to make just the 14th comeback from a 3-1 deficit in NBA history to extend their title reign and may have to do it without All-Star Jayson Tatum, who was carried off the court with a leg injury in the final minutes.
