This will be a tough game on the road.”Herbstreit highlights Ehlinger’s injury to his shoulder, as he’s dealing with pain in his rotator cuff. When he’s healthy, the Longhorns have one of the best dual-threat quarterbacks in the entire nation.In the event that he can’t play the entire game, Herman could hand his offense over to Shane Buechele.Texas and Oklahoma State will kick off at 8:00 p.m. ET.Do you think the Cowboys will shock the Longhorns?
