CHAPEL HILL, N.C. (AP) _ Doctors received permission from the parents of J.R. Reid today to perform surgery on the North Carolina All-American forward after he suffered a stress fracture in his left foot, school officials said.

Sports information director Rick Brewer said Reid was to undergo the operation later today. North Carolina orthopedic surgeon Dr. Timothy Taft was to perform the procedure.

Reid is expected to miss eight weeks, Brewer said, adding that the injury to the fifth metatarsal has ''been developing over the last three or four days.''

The 6-foot-9 Reid, a junior from Virginia Beach, Va., averaged 18 points and 8.9 rebounds for the Tar Heels last season. He was a member of the U.S. Olympic basketball team that won a bronze medal at Seoul last month. He did not play in two games there after suffering a severe bruise during a game.

''We're disappointed,'' North Carolina coach Dean Smith said. ''We hope to have him back for the major part of our season. Dr. Taft has indicated it's a type of injury where surgery is the best alternative.''

The Tar Heels open their season Nov. 19 against Tennessee-Chattanooga in the first round of the Big Apple NIT.
