Oklahoma cornerback Zack Sanchez carted off with apparent leg injury
Sanchez dropped back into coverage and deflected a pass from Red Raiders quarterback Patrick Mahomes, but came down holding his right ankle after the play.
The redshirt junior has been named Big 12 Defensive Player of the Week twice so far in 2015.
Oklahoma ran out to an early 7–0 lead thanks to a Joe Mixon rushing touchdown from 11 yards out.
