It's hard to believe things could've gotten any worse for the Boston Celtics. As if gifting the first two games of the Eastern Conference Semifinals to the New York Knicks wasn't egregious enough, Jayson Tatum suffered a ruptured Achilles in the final minutes of Game 4.

Boston Celtics star Jayson Tatum suffered a torn right Achilles tendon during Monday night's playoff loss to the Knicks, the team announced Tuesday. Tatum has already undergone surgery, and though an exact timetable for his return is not immediately clear, he is expected to miss a significant portion, if not all, of next season.
