WHAT'S AT STAKE
Oklahoma's upset loss to Texas two weeks ago gives the Sooners no margin for error. Their playoff hopes are probably gone with a loss. Texas Tech could claim its third straight Big 12 win and first victory over a ranked team since the 2013 Holiday Bowl.
KEY MATCHUP
Texas Tech QB Patrick Mahomes vs. Oklahoma secondary. Mahomes ranks third nationally in total offense and yards passing per game.
