Joel Embiid, the Kansas center who was widely regarded as the front-runner for the No. 1 overall pick, has suffered a stress fracture to the navicular bone in his right foot. He's scheduled to have surgery on Friday, and could be sidelined for up to six months, sources told ESPN.

"Joel will be unable to participate in any additional workouts, and will not attend the draft in New York," Embiid's agent, Arn Tellem, said Thursday in a statement. "We will have no further comment until after the surgery."
