Series Record: Oklahoma 14-6.
WHAT'S AT STAKE
Texas Tech has shot to the top of the Big 12 under first-year coach Kliff Kingsbury, though Saturday will mark its most difficult test so far. The Red Raiders, who are 1-6 in Norman against Oklahoma coach Bob Stoops, begin a difficult four-week stretch against the Sooners - who hope to jump back into the conference title race with a win.
Oklahoma's secondary vs. Texas Tech quarterbacks Baker Mayfield and Davis Webb. The Sooners lead the country in pass defense - allowing an average of 149.7 yards per game. Mayfield and Webb, meanwhile, lead a Raiders' offense that is second in passing offense with an average of 416.4 yards per game through the air.
PLAYERS TO WATCH
Texas Tech: QBs Mayfield and Webb. Mayfield was the starter for Texas Tech's high-powered offense before a knee injury on Oct. 5 against Kansas sidelined him. The freshman has completed 132 of 201 passes (65.7 percent) for 1,488 yards this season. Since then, Webb - also a freshman - has stepped in and not missed a beat, throwing for 462 yards in last week's come-from-behind win over West Virginia. Kingsbury has declined to name a starter against the Sooners.
Oklahoma: CB Aaron Colvin. One of the nation's best defensive backs, he has 32 tackles, five behind the line of scrimmage, and has broken up three passes. He might see duty on Red Raiders TE Jace Amaro.
