Embiid underwent a successful appendectomy on April 9. Philadelphia coach Nick Nurse said Embiid felt fine in practice on Wednesday before he learned of the situation Thursday morning.
The seven-foot centre’s status is also doubtful should the 76ers advance to the playoffs, as he is in the early stages of recovering from the procedure and will have to undergo separate physical rehab as well, Charania added.
Embiid last played April 6, putting up 34 points, 12 rebounds and four blocks in a loss to Victor Wembanyama and the San Antonio Spurs.
The Cameroonian big man has been limited to just 38 games this season due to knee and oblique injuries, averaging 26.9 points, 7.7 rebounds, 3.9 assists and 1.2 blocks. With his absence on Thursday, Embiid fell short of playing at least half the season for a third consecutive year.
“They’ve played different stretches of the year without him,” Nurse told reporters. “As far as what we do personnel-wise, we’ve got (Adem) Bona, we got (Andre) Drummond and we’ll use them both. And then, hopefully, we can use (Thursday) and (Friday) and Sunday get back to getting used to that scenario again.”
The 76ers are hoping to make the playoffs for an eighth consecutive season and advance beyond the second round for the first time since 2001.
Philadelphia plays the Orlando Magic in the seven-eight play-in game on Wednesday.
