Washington announced on Saturday that Wall will have season-ending surgery in the next few days in Green Bay, Wisc.
"Wizards guard John Wall will undergo a debridement and repair of a Haglund's deformity and a chronic Achilles tendon injury in his left heel," the Wizards said in a news release.
"The procedure will be performed by Dr. Robert Anderson in Green Bay, WI, next week on a day to be determined. Wall is expected to return to full basketball activity in approximately six to eight months."
