CHICAGO (AP) _ Former Chicago Bears coach Mike Ditka underwent hip surgery Saturday and was expected to make a quick recovery after a fall in his home, according to a business partner.

``He is out of surgery and doing fine,'' Ditka's Restaurant managing partner Todd Gunderson said.

He was unsure whether the hip was broken or needed replacement.

Ditka, a Hall of Fame tight end who played most of his career with the Bears and coached them to victory in the 1986 Super Bowl, already has had both hips replaced _ one of them twice.

Gunderson said Ditka was expected to be hospitalized at least overnight, though it was uncertain how long he would be kept.

``Knowing the coach, it's going to be shorter than what they'd normally advise,'' Gunderson said.

Ditka's assistant, Mary Albright, said Ditka was taken by ambulance to Rush Presbyterian-St. Luke's Medical Center after a fall in his Chicago home Friday night. She said hip surgery has become routine for Ditka.

``It'll probably improve his golf game, which he's been crabbing about all week,'' she joked.

Hospital officials would not discuss Ditka's condition.
