ATLANTA -- Hawks star Joe Johnson has had surgery on his injured right elbow and will be begin rehab on Friday.
Johnson underwent arthroscopic surgery Thursday on his elbow in a 25-minute procedure performed by orthopedist Dr. James Andrews at a clinic in Pensacola, Fla. Hawks spokesman Arthur Triche says the "surgery went fine."
The four-time All-Star is expected to be out four to six weeks.
Atlanta announced at the start of Wednesday night's game against Memphis that Johnson would need the surgery to remove a "loose body" in the elbow.
Johnson has said the elbow has caused discomfort "off and on" this season. He told The Associated Press on Wednesday that "it just got unbearable" Tuesday.
