The No. 3 overall selection in the 2014 NBA draft missed his entire rookie season after having surgery in June 2014 to repair a stress fracture in the foot.
Embiid, 21, is expected to have a bone graft procedure similar to the foot surgery of Oklahoma City Thunder forward Kevin Durant. The Sixers announced in July that Embiid needed a second surgery after a routine CT scan in June revealed less healing than anticipated.
Embiid last played with the University of Kansas during the 2013-14 season. Assuming the surgery goes well, the 7-foot, 250-pounder is expected to be ready for training camp for the 2016-17 season. Philadelphia has three other healthy centers on its roster in rookie Jahlil Okafor, Nerlens Noel and Henry Sims.
