CHAPEL HILL, N.C. ? North Carolina’s pursuit of a return to the Final Four is off to a bumpy start. Senior Marcus Ginyard will miss eight weeks after having surgery to repair a stress fracture in his left foot, robbing the Tar Heels of their do-everything swingman who started every game last season. The 6-foot-5 Ginyard averaged 6.9 points and 4.5 rebounds last year for the Tar Heels, who won a school-record 36 games before losing to eventual champion Kansas in the Final Four.
