Boston Celtics superstar Jayson Tatum underwent successful surgery on Tuesday to repair a ruptured right Achilles tendon, an injury sustained during the final minutes of Game 4 in the Eastern Conference semifinals against the New York Knicks. The devastating non-contact injury, which occurred as Tatum lunged for a loose ball, has cast a shadow over the Celtics’ 2025 playoff campaign and their future plans. According to medical experts and team announcements, Tatum is expected to be sidelined for approximately 15 months, potentially missing the entire 2025-26 NBA season. This timeline, while not officially confirmed by the Celtics, aligns with the severity of Achilles injuries and the cautious approach required for a full recovery.
The injury occurred with 2:58 remaining in the fourth quarter of Boston’s 121-113 loss to the Knicks, a game in which Tatum had been dominant, scoring 42 points, his playoff high. As he dove for a loose ball, his right leg buckled, and he collapsed in agony, clutching his Achilles. Unable to bear weight, Tatum was assisted off the court and later seen in a wheelchair, visibly emotional. An MRI on Tuesday confirmed the worst fears: a complete Achilles tendon rupture, necessitating immediate surgery. Dr. Brian Sutterer, a sports medicine physician, noted that Tatum’s movement mirrored classic signs of an Achilles tear, a diagnosis echoed by other experts like Dr. Jesse Morse, who estimated a recovery timeline of 10-12 months, though 15 months is now cited for a player of Tatum’s caliber to ensure full strength and confidence.[](https://www.talkbasket.net/197214-doctor-raises-serious-concern-over-jayson-tatums-injury)
Achilles injuries are notoriously challenging, both physically and psychologically. Dr. John Positano, quoted in reports, emphasized that recovery typically spans 4-6 months for basic healing, but returning to elite athletic performance often takes longer—up to a year or more. The psychological hurdle is significant, as athletes fear re-injury during explosive movements like jumping or cutting, critical to Tatum’s game. At 27, Tatum’s youth is an advantage, with examples like Kevin Durant, who returned to All-Star form after a similar injury at 32, offering hope. However, Durant’s recovery took over a year, and Tatum’s 15-month projection reflects a conservative approach to protect his long-term career.
For the Celtics, Tatum’s absence is a crushing blow. Trailing 3-1 in their series against the Knicks, Boston faces elimination without their cornerstone, who averages 28.1 points and 11.5 rebounds in the playoffs. The team has shown resilience, going 9-2 without Tatum this season, but his role as a defensive magnet and offensive hub is irreplaceable. Coach Joe Mazzulla has preached a “next man up” mentality, with players like Jaylen Brown and Derrick White expected to step up. Long-term, Tatum’s injury could force roster changes, as president of basketball operations Brad Stevens navigates second-apron restrictions and a potential retooling of the championship core.
Celtics fans and the NBA community have rallied around Tatum, with players like LeBron James expressing support. While the team expects a full recovery, the road ahead is daunting. Tatum’s determination and youth fuel optimism, but the 15-month timeline underscores the injury’s severity, leaving Boston to recalibrate without its star.
