Wisconsin starting quarterback Alex Hornibrook is going through concussion protocol and may miss Saturday's game at Northwestern.
Coach Paul Chryst told WIBA radio on Friday that Hornibrook is questionable for the game, and that sophomore Jack Coan would start in his place if the fourth-year junior cannot play. Chryst said the staff knew early in the week that Hornibrook might miss the game, and Coan has received extra work in practice.
"Jack has had really the week to start preparing and not knowing exactly when or if we'd get Alex, if he'd be cleared for this week," Chryst told WIBA.
