North Carolina said Mack Brown has had his right knee replaced by a surgeon who once played for the football coach.

Team spokesman Jeremy Sharpe said Tuesday that the 67-year-old coach underwent the procedure Monday that was performed by one of Brown's former players.

Dr. Michael Bolognesi -- who played defensive back for Brown from 1989 to 1993 -- said the surgery won't affect the coach's summer schedule. He was discharged later Monday afternoon.
