• Iowa running back Barkley Hill and defensive back Ruben Lile suffered season-ending injuries and are expected to redshirt this season.

Hill, a true freshman, suffered a torn anterior cruciate ligament on an 8-yard touchdown run in Saturday's scrimmage.

Lile, a freshman, also has a knee injury, but the exact nature of it was not released.
