MADISON, Wis. (AP) — Wisconsin coach Bret Bielema says star running back Montee Ball won’t be ready for camp after suffering a concussion during a street fight. According to the Wisconsin State Journal, Bielema said during a taping of a show at WISC-TV studios in Madison on Thursday that Ball won’t be ready when practice begins Monday. The Badgers open the season at home Sept. 1 against Northern Iowa. Bielema gave no indication Ball would suffer any long-term problems. He said Ball’s absence will spare last year’s Heisman Trophy finalist hits and give other backs more repetitions. Police said five men knocked Ball down as he was walking near campus early Wednesday. The men kicked him in the head and chest before fleeing.
