Wisconsin's Hornibrook sidelined with concussion

Wisconsin quarterback Alex Hornibrook won't play Saturday at Northwestern due to a concussion, head coach Paul Chryst confirmed pregame, per the Big Ten Network.

Hornibrook will be replaced in the starting lineup by Jack Coan, a sophomore who's attempted just five passes in his college career.

Hornibrook matched a season high with three touchdowns last week in the Badgers' blowout victory over Illinois. He's thrown for 1,251 yards with 11 touchdowns and six interceptions across seven contests this season.
