STATE COLLEGE, Pa. -- Senior outside linebacker and co-captain Sean Lee won't play tonight because of a sprained left knee, but his teammates are picking up the slack.
Navorro Bowman hasn't missed a beat after sitting out the last two games with a groin injury he re-aggravated in the opener. Both Bowman and Josh Hull have contained Iowa's run game for the most part, and Bani Gbadyu also is chipping in. Bowman makes a huge difference on run plays, as he's constantly in the backfield.
