Doctors delayed knee replacement surgery for Wisconsin football coach Barry Alvarez on Tuesday after discovering an infection in his severely arthritic right knee.
Doctors at the Mayo Clinic said the infection would be treated and no date has been set for the replacement surgery.
The 52-year-old Alvarez will remain hospitalized and will not attend Saturday's game between the 20th-ranked Badgers and No. 25 Minnesota in Minneapolis, although he will talk with his coaches by telephone from his hospital room, according to a statement issued by the Wisconsin sports information office.
"The timetable for his return to coaching cannot be determined at present," the statement said.
John Palermo, Wisconsin's assistant head coach and defensive line coach, is acting head coach until Alvarez returns.
Alvarez coached against Michigan and Ohio State from the press box.
The knee has caused Alvarez severe pain ever since he re-injured the joint while attending an exhibition game in Madison between the Green Bay Packers and the Denver Broncos on Aug. 23. Internal bleeding was filling the joint with fluids.
