NOTRE DAME, Ind. -University of Notre Dame football coach Charlie Weis underwent successful surgery for replacement of his right knee this morning at Memorial Hospital in South Bend.
"The severe deterioration of the bone explains the severe pain he suffered the last three weeks," said Dr. Willard G. Yergler, M.D., of South Bend Orthopaedics Associates and director of sports medicine for the Notre Dame football program, who performed the hour-long surgery.
"With the knee replacement, he'll start walking this afternoon."
Weis is expected to be released in a day or two and then begin several months of rehabilitation.
A final decision has yet to be made on what to do with Weis' left knee that was injured during Notre Dame's win over Michigan in September.
