Jayson Tatum exits Game 4 unable to place weight on right leg

Jayson Tatum exited Game 4 of the Eastern Conference semifinal series featuring the Boston Celtics and New York Knicks with just under three minutes remaining in the fourth quarter. 

Tatum dove for a loose ball that resulted in an OG Anunoby break-away dunk, and seemingly sustained a non-contact injury to his right ankle or lower leg. 

Boston's trainers tended to a writhing Tatum, who ultimately was escorted out, unable to place weight on his right leg. A few minutes later, the ESPN broadcast panned to Tatum being wheeled to the locker room in a wheelchair.
