Longtime Wisconsin assistant Greg Gard will take over as interim head coach.

In his 14 years as the Badgers' head coach, Ryan recorded the most wins in school history (364), finishing with a final record of 172-68 (.717) in Big Ten play, the highest winning percentage in conference history. With a career record of 747-233, Ryan finishes his career ranked 27th on the NCAA?s all-time wins list. Wisconsin is 7-5 this season.

Ryan, who turns 68 next week, had said in a statement last June that he would coach this season and then step down.
