A Familiar Scene: Tatum Walks Off in the Third Quarter

For the third time in three postseasons, Jayson Tatum left a playoff game early with an injury. On Thursday night, during the third quarter of Game 6 against the Philadelphia 76ers at Xfinity Mobile Arena, the Celtics forward walked to the locker room with an apparent left calf injury, sparking immediate concern among fans and teammates. Tatum had shown signs of discomfort throughout the game, even after briefly returning to the bench with an ice pack on his calf. He did not re-enter the contest, and Boston fell 106-93, evening the series at 3-3 and setting up a decisive Game 7 in Boston on Saturday.

Conflicting Accounts: Injury or Just Stiffness?

After the game, Celtics coach Joe Mazzulla downplayed the severity, telling reporters that Tatum “went in the back, just got stretched, got some treatment. That was about it.” Tatum himself said he was “not overly concerned,” explaining that his leg was “a little stiff” when he came out of the third quarter. He clarified that the stiff leg was not the one he injured last year, when he tore his Achilles tendon in Game 4 of the 2025 Eastern Conference Semifinals. Despite these reassurances, independent medical voices offered a more cautious view. Dr. Jesse Morse wrote on social media that “depending on the specifics of the injury, there is a chance he misses this game,” referring to Game 7. ESPN.com characterized the issue as “an apparent calf injury,” and multiple reporters noted that Tatum headed to the locker room with Celtics trainer Nick Sang.

A Season of Recovery Hangs in the Balance

Tatum spent most of the regular season recovering from the torn Achilles tendon he suffered in last year’s playoffs. He returned to play 16 games, averaging 21.8 points, 10.0 rebounds, 5.3 assists, 1.4 steals and 0.2 blocks per game on 41.1% shooting from the field and 32.9% from three-point range. His comeback, combined with Jaylen Brown’s rise and contributions from role players, helped the Celtics secure the second seed in the Eastern Conference. Thursday’s injury cut short what was shaping up to be a strong performance: in 29 minutes, Tatum had 17 points, 11 rebounds and three assists, shooting 46.2% from the field and 33.3% from three. Neither he nor Brown reached 20 points, underscoring Boston’s offensive struggles without their star.

Momentum Shifts: The 76ers’ Resurgence and the Embiid Factor

The Celtics have now lost two straight games, surrendering the series momentum they built with a 3-1 lead. Philadelphia’s comeback has been fueled by the return of Joel Embiid, whose presence has added a new variable that Boston has struggled to counter. Neemias Queta and Sam Hauser have held down the frontcourt but are no match for Embiid and Paul George, who have been getting whatever they want offensively. Chemistry issues have also surfaced for the Celtics, who appear to be a team struggling to remember what made them successful over the past six months. The back-to-back losses have left Boston facing a must-win Game 7 at home, with Tatum’s status now the central question.

What Comes Next: Game 7 and the Uncertain Fate of Boston’s Star

Tatum has stated he “expects to play” in Game 7, and the Celtics have not issued any official clarification contradicting that. However, the team has not confirmed his availability, and the conflicting signals — Mazzulla’s dismissal of an injury versus Tatum’s admission of stiffness and the visible ice pack — leave room for doubt. If Tatum is sidelined or compromised, the Celtics will be hard-pressed to stop a Sixers team that has all the momentum. Boston has lost all three playoff games in which Tatum left early due to injury: Game 7 of the 2023 Eastern Conference Finals (ankle), Game 4 of the 2025 Eastern Conference Semifinals (Achilles), and now Game 6 of this series.

A Franchise’s Fate Rests on One Game — and One Calf

The Celtics entered Thursday as favorites to close out the series against an inconsistent 76ers squad. Instead, they now face a crisis that could end their season prematurely. Tatum’s health — whether he plays at full strength, at less than 100%, or not at all — will likely determine the outcome of Game 7. For a player who has already overcome a nine-month rehabilitation from a torn Achilles, the prospect of another injury setback is particularly cruel. But as Tatum himself said, he was not overly concerned. Saturday will reveal whether that confidence is justified or whether the Celtics’ championship aspirations will once again be derailed by an untimely injury to their star.

The bottom line

• Jayson Tatum left Game 6 with a left calf injury but expects to play in Game 7 on Saturday.
• Coach Joe Mazzulla said Tatum was not injured, only stretched, while Dr. Jesse Morse warned he could miss Game 7.
• Tatum missed most of the regular season recovering from a torn Achilles tendon in the same leg he injured last year.
• The Celtics have lost two straight games and all three playoff games Tatum has left early due to injury.
• Philadelphia’s Joel Embiid has been a key factor in the 76ers’ comeback, posing matchup problems for Boston.
• Game 7 in Boston will determine whether the Celtics advance or face another early playoff exit.
