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.

Tatum went down in the fourth quarter after planting his foot awkwardly. He was in visible pain as trainers rushed to his side and was later taken to the locker room in a wheelchair. The Celtics have not released a diagnosis on Tatum, who will undergo an MRI on Tuesday.
