In a stunning development that has sent shockwaves through the NBA, Boston Celtics superstar Jayson Tatum has been ruled out for Game 7 of the team's first-round playoff series against the Philadelphia 76ers. The official diagnosis is "left knee stiffness," but the bigger story might be who made the final call—and it wasn't Tatum himself.

Celtics head coach Joe Mazzulla revealed during his pregame press conference on Saturday night that the decision to sideline the six-time All-Star came from the team's medical staff. "He came in today with knee discomfort and we decided... for him not to play," Mazzulla explained, emphasizing the collective "we" that made the tough call. "We thought that was in his best interest."

The news marks a dramatic reversal from just 24 hours earlier, when Mazzulla had confidently stated during a media call that Tatum would be on the court for the winner-take-all showdown at TD Garden. Even Tatum himself had downplayed the injury after a limited second-half performance in Game 6 on Thursday, making it seem like business as usual. But when the knee stiffness flared up Saturday morning, the Celtics' medical team stepped in to protect their franchise cornerstone.

This isn't the first time Boston has faced the Sixers without Tatum this season—they opened the regular campaign with a home loss to Philadelphia while he was sidelined. Now, with their season hanging in the balance, the Celtics will need to channel that same resilience to force a different outcome. The good news? Mazzulla described Tatum as "day-to-day," meaning if Boston can survive Game 7, their star could be back for the next round.

For now, it's all hands on deck for a Celtics team that must dig deep without its leader. The stakes couldn't be higher, and the basketball world will be watching to see if Boston can rise to the occasion.
