FILE - In this Saturday, March 29, 2008, file photo, Penn State defensive coordinator and secondary coach Tom Bradley, right, stands on the sidelines with Sean Lee during spring football practice in State College, Pa. If there's any position that can take a roster hit at Penn State, it's linebacker, a unit blessed with a mix of experience and youthful potential. And that's not even including captain Sean Lee, who won't play in Saturday's Blue-White scrimmage out of precaution for the knee he injured last year. (AP Photo/Carolyn Kaster, File)
