Boston basketball fans braced for a seismic shift on Saturday evening as the Boston Celtics announced, just hours before tip-off, that superstar Jayson Tatum would not play in the decisive Game 7 of their first-round playoff series against the Philadelphia 76ers. The news sent shockwaves through TD Garden and across the NBA, with the fate of Boston’s postseason suddenly hanging in the balance.
Tatum, who had been a pillar for the Celtics since returning from a devastating right Achilles tendon rupture last May, was ruled out due to left knee stiffness. The development was as abrupt as it was disheartening for Celtics supporters: less than 24 hours earlier, the team’s injury report was clean, and Tatum himself had downplayed any health concerns after sitting out the final quarter of Game 6 in Philadelphia. He told reporters, “My leg was just a little stiff when I came out in the third quarter. But just kind of assessing the moment, like, the game was a little out of reach. We took the starters out.”
Coach Joe Mazzulla, who echoed Tatum’s optimism after Game 6, was forced to change his tune on Saturday. “He just came in today with knee discomfort,” Mazzulla said before Game 7, adding, “The medical team and myself decided for him not to play.” According to Celtics reporter Noa Dalzell, Mazzulla described the issue as “back-of-the-knee stiffness” and clarified that Tatum was now considered “day-to-day.”
The timing could hardly have been worse for Boston. After surging to a 3-1 series lead, the Celtics dropped back-to-back games to a resurgent Sixers squad, led by the dynamic trio of Joel Embiid, Tyrese Maxey, and Paul George, with rookie VJ Edgecombe stepping up in critical moments. Historically, the Celtics have never lost a playoff series after leading 3-1 (32-0), while the 76ers have never come back from such a deficit (0-18). But with Tatum sidelined, the odds and the narrative suddenly shifted.
Tatum’s absence left a gaping hole in Boston’s lineup. In the first six games of the series, he averaged 23.3 points, 10.7 rebounds, and 6.8 assists per contest, shooting an efficient 47.5% from the field and 36.5% from beyond the arc. His two-way impact and leadership were instrumental in Boston’s regular-season success, even as he missed most of the year recovering from his Achilles injury. The Celtics managed a strong 41-21 record before his March return, including a regular-season split with Philadelphia, but replacing Tatum’s production in a win-or-go-home scenario would be a tall order.
Boston’s Game 7 starting lineup reflected the magnitude of the challenge. With Tatum out, Mazzulla turned to Derrick White, Baylor Scheierman, Jaylen Brown, Ron Harper Jr., and Luka Garza—a group that had not logged a single minute together all season. Jaylen Brown, who has seen his scoring dip in the postseason, and Derrick White, who has struggled against the Sixers, suddenly found themselves thrust into even larger roles. The Celtics’ depth would be tested like never before.
The Sixers, meanwhile, got a double dose of good news ahead of Game 7. Paul George, who had missed the morning shootaround due to illness, was upgraded to available and slotted into the starting lineup alongside Tyrese Maxey, VJ Edgecombe, Kelly Oubre Jr., and Joel Embiid. Embiid, just weeks removed from an appendectomy, was cleared to play his fourth game since returning from surgery. Sixers coach Nick Nurse acknowledged George’s illness but expressed confidence: “We’re expecting him to give it a shot.”
For Philadelphia, the high-stakes showdown at TD Garden represented both a chance at redemption and an opportunity to rewrite franchise history. The Celtics and Sixers were meeting for the 23rd time in the postseason—the most between any two teams in NBA history. Boston had won six consecutive playoff series against Philadelphia dating back to 1982, and had repeatedly been the roadblock in Joel Embiid’s playoff journey. In fact, Tatum and the Celtics had eliminated Embiid-led Sixers squads three times since 2018.
The drama surrounding Tatum’s injury unfolded rapidly. On Friday, the Celtics’ official health update listed no injuries. But by 1:30 p.m. ET Saturday, Tatum appeared on the injury report as questionable with left knee stiffness. Less than four hours later, he was ruled out entirely. The sudden change left fans and analysts alike scrambling for answers. After Game 6, both Tatum and Mazzulla had minimized the concern, with Tatum suggesting he would have played had the game been closer and Mazzulla insisting, “He just stretched and got some treatment, that’s it.”
But the specter of Tatum’s recent Achilles injury loomed large. At less than a year removed from surgery, any lower-body issue was bound to raise alarms. The Celtics’ decision to err on the side of caution reflected a broader trend in the NBA, where teams have become increasingly vigilant about player health in the wake of high-profile injuries—such as Tyrese Haliburton’s Achilles tear after playing through a calf injury in last year’s Finals.
For Boston, the stakes extended beyond just one game. If the Celtics managed to prevail without Tatum, they would face the New York Knicks in the second round, with Game 1 scheduled for Monday night. Tatum’s status for a potential next series remained up in the air, with Mazzulla labeling him “day-to-day” and hinting at a possible game-time decision should Boston advance. On the flip side, a loss would usher in a long offseason of uncertainty regarding the health and future of their franchise cornerstone.
The Sixers, emboldened by the return of their stars and the absence of Boston’s, were eager to seize the moment. Coach Nick Nurse’s faith in his squad was evident, despite the late-breaking health drama of his own. “We’re expecting him to give it a shot,” Nurse said of George, who joined Embiid and Maxey in a formidable starting five. Rookie VJ Edgecombe, meanwhile, continued to impress, providing timely contributions on both ends of the floor.
As tip-off approached, the atmosphere inside TD Garden was electric, tinged with anxiety and anticipation. Could Boston’s supporting cast rise to the occasion and preserve the franchise’s immaculate record when leading 3-1 in a series? Or would Philadelphia finally break through, rewriting an ignominious chapter of playoff futility? With both teams’ seasons on the line, Game 7 promised to deliver drama worthy of the NBA’s greatest rivalry.
With Jayson Tatum’s status uncertain for any future games, all eyes remained fixed on Boston’s response to adversity and Philadelphia’s pursuit of history. The outcome of this Game 7 would not only decide who advanced, but also set the tone for the rest of the NBA postseason.
