No. 12 Oklahoma State got a boost from third-string, true freshman quarterback Shane Illingworth to survive an upset bid from Tulsa, 16-7, on Saturday at Boone Pickens Stadium. 

Here are five takeaways the Cowboys’ up-and-down escape:

Third-stringer saves the day

Oklahoma State starting quarterback Spencer Sanders injured his right ankle on the first offensive possession of the game, and he tried to tough it out, but after a fumble on the first snap of the second possession, Sanders headed to the locker room and didn’t return.

Junior-college transfer Ethan Bullock entered, playing the rest of the first half and briefly into the third quarter. But after an interception, he was pulled in favor of four-star recruit Shane Illingworth.

The true freshman brought an immediate spark to the offense, throwing twice to Tylan Wallace on his first series and leading a touchdown drive that gave OSU a 10-7 lead.
