NORMAN, Okla. — Kansas State starting quarterback Jesse Ertz has left the game against No. 19 Oklahoma with an apparent injury to his throwing shoulder. Oklahoma running back Samaje Perine also left the game with an injury.

Ertz left in the second quarter, holding his right arm, and was replaced by backup Joe Hubener. Ertz returned for the first two plays of the third quarter, but after one incomplete pass that was way off the mark, came out of the game again. He completed 8 of 14 passes for 68 yards and was the Wildcats’ leading rusher with 40 yards and a touchdown on seven carries.

Perine left in the first quarter with an apparent leg injury. Joe Mixon took over the primary running back duties for the Sooners.
