(Radio Iowa) – Iowa State hosts 18th ranked Oklahoma in prime time tomorrow night. The Sooners have their backs to the wall after losing at home to open Big-12 play. ISU will allow 15 thousand fans in Jack Trice Stadium but coach Matt Campbell says that won’t change their approach.

The Sooner defense is only giving up 60 yards on the ground per game and Campbell says their success begins with a veteran defensive line.

Oklahoma gave up 334 yards of passing in the loss to K-State but Campbell says the Sooner secondary has talent and speed.
