Joel Embiid, who was considered the favorite to be the overall No. 1 pick in next week's NBA Draft, will undergo surgery for a stress fracture in his right foot Friday, his agent confirmed in a statement.

"Joel Embiid suffered a stress fracture to the navicular bone in his right foot," Arn Tellem said in the statement. "He is scheduled to have surgery tomorrow. Joel will be unable to participate in any additional workouts, and will not attend the draft in New York. We will have no further comment until after the surgery."

ESPN first reported the injury, which Tellem said Embiid had suffered in a workout sometime over the last few days.

The 7-footer from Kansas was in the mix to be the top pick, but the injury could push the Cleveland Cavaliers toward Jayhawks forward Andrew Wiggins or Duke's Jabari Parker.

Embiid missed the postseason in March with a stress fracture in his back, which some teams believe could be a chronic issue. He averaged 11.2 points, 8.1 rebounds and 2.6 blocks as a freshman last season.

Embiid, 18, is relatively new to the game of basketball.

He had been scheduled to work out for the Milwaukee Bucks this week, an indication he was not told by the Cavaliers that he would be the top overall pick.

He was the first of the lottery prospects to visit Cleveland. The Cavaliers have not hired a head coach but were hopeful the search to secure their third coach in three seasons would be complete before the June 26 draft.

Cleveland drafted No. 1 overall in 2013 and UNLV's Anthony Bennett was a non-factor as a rookie. He missed out on the pre-draft process following shoulder surgery last spring.
