UNC coach Roy Williams has surgery to remove tumor

(CBS) -- North Carolina basketball coach Roy Williams underwent robotic partial nephrectomy at UNC Hospitals early Wednesday to remove a tumor from his right kidney, a school spokesperson confirmed to CBSSports.com.

The procedure lasted more than three hours.

Doctors discovered the presence of a tumor during Williams' physical earlier this month. They said they expect the Hall of Famer to be available to coach when official practice begins the weekend of October 13. But they added that Williams, 62, might require another procedure next month to remove a second tumor from his left kidney.

"The surgery went well and according to plan," said Dr. Eric Wallen, one of the men who performed the procedure. "Coach Williams did great. I fully expect him to coach this season and for years to come. He could miss some practice time if we perform another procedure sometime in October, but he would be able to resume his coaching duties prior to the start of the regular season."

Williams became a head coach in 1988 at Kansas. He replaced Matt Doherty at UNC in 2003 and has won two national championships. The first was in 2005. The second was in 2009.

"Our thoughts and prayers are with Coach Williams and his family for a full recovery,” said UNC athletic director Bubba Cunningham. "Obviously his health and prognosis are my greatest concerns. He's in great hands with the medical staff at UNC Hospitals. The basketball team is also in outstanding hands with [assistants] Steve Robinson, CB McGrath, Hubert Davis and Joe Holladay. As Coach Williams frequently says, he has the best staff in the country and I know they will do an excellent job as Coach Williams recuperates. We will be ready for his return as soon as he is able to do so, but I have stressed to him that he returns only when he has been given the medical approval and he is ready to do that. Hopefully that will be soon and for a long, long time to come."
