Kansas State (3-4, 1-3 Big 12) at No. 8 Oklahoma (6-1, 3-1), 3:30 ET (Fox).

Line: Oklahoma by 24½.

Series record: Oklahoma leads 75-19-4.

WHAT'S AT STAKE?

Oklahoma bounced back from its loss to Texas with a rousing 52-27 win over TCU last week. The Sooners would like to put together another sound defensive effort under interim defensive coordinator Ruffin McNeill. They can't afford to slip if they want to reach the College Football Playoff again. Kansas State is building momentum, too. The Wildcats rolled past Oklahoma State 31-12 in their last game, and then had an off week to prepare for the Sooners.

KEY MATCHUP

Oklahoma's defense vs. Kansas State's running game. Kansas State has averaged 305 yards rushing its past two games. Oklahoma has struggled to get its defense off the field at times. Army had the ball for more than 44 minutes in a game the Sooners barely escaped with a win. Kansas State is fully capable of bleeding the clock and keeping Oklahoma's high-octane offense on the sideline.
