One of the biggest question marks heading into the first-round playoff matchup between the Boston Celtics and Philadelphia 76ers has now received a definitive, if unwelcome, answer for the opening games of the series.

Joel Embiid, the 76ers’ perennial All-Star center and former MVP, has not played since April 6 after undergoing an emergency appendectomy. He missed the final three games of the regular season and sat out Philadelphia’s Play-In Tournament victory over the Orlando Magic on Wednesday. With the Eastern Conference series set to tip off on Sunday in Boston, Embiid’s availability has been the central storyline for both clubs. On Thursday, NBA insider Shams Charania delivered the clarity that had been anxiously awaited — and it was not the one Celtics fans were hoping to hear.
“Sixers are preparing for battle against the Celtics without Joel Embiid at least to start the series,” Charania reported on ESPN. “He’s only a weekish removed from surgery for that appendicitis. And so, he’s very much in the recovery phase of this… This is a serious issue that Joel Embiid had a week ago. He’s still trying to recover.”

The timeline is unforgiving. An emergency appendectomy is no minor procedure, and medical protocol demands a deliberate, phased recovery. Charania emphasized that once Embiid clears the initial post-surgical healing, he will still require structured rehabilitation before he can even be evaluated for basketball activity. That two-stage process — recovery followed by rehab — makes an immediate return highly improbable.
Yet there is a sliver of optimism. For the first time since the surgery, Embiid was with the 76ers on Wednesday night during their Play-In win over the Magic. His presence on the bench, even in street clothes, signaled progress and offered his teammates a psychological lift at a critical moment. It was a quiet but meaningful step, reminding everyone that the seven-time All-Star remains locked in with the group despite his physical limitations.
Still, the analytical reality is stark. The 76ers will open the series without their most dominant interior presence, their leading scorer, and the one player capable of altering the Celtics’ preferred style of play. Boston, fresh off a strong regular-season campaign, now faces a Philadelphia team that must find answers through committee defense, adjusted offensive sets, and increased minutes for supporting cast members. The Celtics’ locker room will have received Charania’s update as welcome news — a blindside blitz of good fortune that simplifies their defensive assignments and offensive game-planning for at least the first two games.
How long the absence lasts remains the only lingering variable. Time will tell if or when Embiid is able to return against Boston. Based on Charania’s reporting and the medical realities of appendicitis recovery, the most prudent projection is that the 76ers will begin the series shorthanded, with Embiid’s potential reappearance still days — or possibly longer — away.
For now, the spotlight shifts squarely onto Philadelphia’s depth and resilience. The Celtics have been handed a tangible edge before the ball even goes up on Sunday. Whether that edge proves decisive will depend on how well the 76ers adapt in Embiid’s continued absence — and how quickly the big man can navigate the demanding road back from surgery. The series has its first major storyline, and it is one the Celtics will be more than happy to exploit.
