Awful offseason for Terry Francona -- the Cleveland skipper just revealed he was recently treated for a bad staph infection ... and had to get part of a bone in his foot removed in the process.
The 61-year-old broke down his health struggles with reporters from Spring Training on Friday ... saying he's currently in a walking boot and using crutches after having cement put in his foot.
Francona says he was initially treated for gout back in November ... but the pain continued for months. When he got checked out at the Cleveland Clinic, docs discovered the staph infection in his toe.
