University of North Carolina men’s basketball coach Roy Williams underwent a roboticpartial nephrectomy at UNC Hospitals this morning to remove a tumor from his right kidney.

Dr. Eric Wallen, professor of urology at UNC, and co-surgeon Dr. Mathew Raynor led the surgical team, which took three and a half hours to complete the operation. Doctors discovered the presence of the tumor during a physical earlier this month.

Dr. Wallen says Williams, 62, should be able to coach when the Tar Heels begin practice for the 2012-13 season on Saturday, October 13th. Williams may have a second surgery to remove a tumor from his left kidney at a later date and could be sidelined for a few practices.
