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 reportedly 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.

Jayson Tatum suffered a torn Achilles tendon during Monday night's Game 4 of the Eastern Conference semifinal series between the Boston Celtics and New York Knicks. The Celtics star left the game late in the fourth quarter after he went down on the court from the non-contact injury.

On Monday, Tatum earned his 28th playoff game with a 20+ point half, the most of any NBA player in the span of 2020 and 2025. He finished the first half of the game with 20 points, six rebounds, two steals and two blocks.

Jayson Tatum heard it all after the Celtics blew Game 2 to the Knicks. After a bounce-back performance, he spoke about the perspective needed when it comes to being Boston's top player.

Meanwhile, Tatum, who is 12 for 43 in this Knicks series overall (including 5 of 20 from 3), has missed eight of 10 shots and all four of his 3-pointers in 19 clutch minutes so far in this postseason. It's an extension of a regular season in which he shot 6 for 31 from 3 and just 65% from the free-throw line during clutch minutes.
