Iowa State fell behind 21-0 and then 28-7 but has battled back despite injuries to its starting quarterback, tight end, weakside linebacker, defensive end and presumably its starting running back, although there's no word on why Aaron Wimberly isn't playing.
At the half against No. 19 Oklahoma State, Iowa State is down 28-20.
The Cowboys reeled off a quick 14 points before five minutes on a long scoring drive and a Justin Giblert pick-six off ISU quarterback Sam Richardson, then took a 21-0 lead on a Clint Chelf pass to Charlie Moore.
Iowa State woke up Jack Trice Stadium with a Richardson touchdown pass to Quenton Bundrage — a 22-yard backshoulder fade — and has looked in-sync since then, giving up another touchdown but scoring twice more: a somersault flip over the pylon by DeVondrick Nealy and juggling catch made by Bundrage in the corner of the end zone.
Backup quarterback Grant Rohach provided the last touchdown pass, one of his three completions in relief of Richardson, who was crunched from behind while he slid and was administered a concussion test on the sideline. Rohach, the redshirt freshman from California, led the Cyclones on an 11-play, 54-yard drive on his first series, with Jeff Woody converting a fourth-and-one to keep the drive alive.
Tight end E.J. Bibbs has three receptions for 53 yards but went to the sideline midway through the second quarter with what looked to be a thigh injury and has stayed on the bench since then.
Wimberly, injured two weeks ago against Texas Tech, hasn't seen any game action. Redshirt freshman Luke Knott hasn't played — his brother, Jake, tweeted he was injured — and starting left end Willie Scott is in sweats on the sideline.
Chelf got the start for Oklahoma State over J.W. Walsh and has struggled for the most part, completing 8-of-21 passes for 64 yards and a touchdown. He had 57 net yards rushing.
