Jayson Tatum will miss at least the rest of the playoffs and beyond. The Celtics announced Tuesday that Tatum underwent successful surgery to repair a ruptured right Achilles tendon. Considering the severity of the injury, Tatum will be expected to miss a significant amount of time. Here’s the full statement from the Celtics:
