BOSTON — When Jayson Tatum toppled to the court, writhing in pain and grabbing at his right foot late in the Celtics' Eastern Conference semifinals Game 4 loss to the New York Knicks, it looked like a potentially season-altering injury.
Boston's worst fears are now confirmed.
Tatum had surgery Tuesday to repair a ruptured right Achilles tendon that will sideline him for the remainder of the playoffs, the team announced.
The Celtics provided details on the extent of Tatum's injury and announced news of the surgery a day after the six-time All-Star went down in the Celtics' 121-113 Game 4 loss to the New York Knicks. It puts the hopes of the defending champions repeating and Tatum's playing status for next season in doubt.
They did not give a timetable for his return, but said a full recovery was expected.
When Kevin Durant tore his Achilles tendon during the 2019 NBA Finals, he wound up missing the entire 2019-2020 season.
The 27-year-old Tatum is leading the Celtics in points (28.1), rebounds (11.5) and assists (5.4) per game for the second straight postseason.
The Knicks lead the Celtics 3-1 in their Eastern Conference semifinals series. Game 5 is in Boston on Wednesday night.
