The Inquirer's Keith Pompey reported earlier Saturday that Embiid will have a second surgery after having a setback in the healing process of his right foot, which caused him to miss the entire 2014-15 season.
The 7-foot Embiid, 21, was the No. 3 overall pick in the 2014 draft out of Kansas. A stress fracture in the navicular bone of his right foot sidelined him for the entirety of his rookie year, an injury that forced another gifted big man, Yao Ming, to retire earlier than expected.
Embiid has not played in a competitive game since March 1, 2014 when Kansas played Oklahoma State.
The Sixers drafted Duke center Jahlil Okafor third overall in this year's draft.
