The gruesome Achilles injury Jayson Tatum suffered added salt to the wounds of the team's fans after the Boston Celtics lost in Game 4 against the New York Knic

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.

Orthopedic surgeons call Achilles' tears some of the most difficult injuries an athlete can sustain, and recovery can take longer for pro athletes.

The Celtics announced Tuesday that Jayson Tatum suffered a ruptured Achilles tendon in his right foot on Monday against the Knicks.

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.
