Wisconsin's Bo Ryan announced in June that he planned to retire after this season.

Now he's not so sure.

"Everybody kind of thinks they know when they're ready to retire; I'm not totally sure," Ryan said at a golf tournament Wednesday, according to PostCrescent.com. "[Wisconsin AD] Barry [Alvarez] said I could change my mind at any time. I haven't submitted any papers yet. I haven't submitted anything. ... So I might stay for another four or five [years]."
