The Boston Celtics are still awaiting official word on Jayson Tatum's injury suffered in Game 4 of the Eastern Conference semifinals against the New York Knicks, but early indications are they aren't expecting good news.

The Boston Celtics star was ruled out for the rest of the playoffs with a torn right Achilles tendon, the team announced. Tatum underwent surgery on Tuesday, less than 24 hours after he initially sustained the injury. A timeline for his return is not yet known, but he is expected to make a full recovery.
