Surgeons Robert Watkins Sr. and Robert Watkins Jr. released a statement Saturday saying the surgery was "uneventful" and that Howard was resting comfortably. The procedure took place Friday in Los Angeles.
Howard had a herniated disc and had some fragments removed. He is expected to begin what the doctors are calling a "core stabilization" program in three weeks.
Howard will miss the remainder of the Orlando season, including the playoffs. He will not play for the United States this summer at the London Olympics.
