If the Boston Celtics extend their season by beating the visiting New York Knicks in Game 5 of the Eastern Conference semifinals Wednesday night, they will do so without leading scorer Jayson Tatum.

Jayson Tatum today underwent successful surgery to repair a ruptured right Achilles tendon.

Jayson Tatum was carried off the court with a lower right leg injury with 2:58 remaining in Game 4 of the Eastern Conference semifinals on Monday night.
