Here are a few last-minute tidbits before tonight's Texas Tech-Oklahoma game.
WHAT'S AT STAKE: Something has to give tonight. The Sooners have a nation-best 23 game winning streak. But Texas Tech is 10-0 for the first time since 1938 and will carry a 12-game winning streak that is the longest in the country to start the day.
A Texas Tech victory would give the Red Raiders their first birth in the Big 12 championship game against Missouri on Dec. 6.
An Oklahoma victory would throw the South Division into a three-way tie for the lead. Next week, Oklahoma travels to Oklahoma State, Texas hosts Texas A&M on Thanksgiving night and Baylor will visit Texas Tech. If there's a three-way tie at the end of that day, the Bowl Championship Series standings will be used to determine which team will advance to the championship game.
INJURIES: Oklahoma's banged-up defense will have some replacements. Starting defensive ends Auston English and Alan Davis both are out with sprained knees. That will mean that redshirt freshman Frank Alexander and Jeremy Beal will get the starts, with converted linebacker J.R. Bryant and Pryce Macon thrust into key reserve roles. Steady middle linebacker Ryan Reynolds has been out since the Texas game with a torn ACL. Redshirt freshman Austin Box will get the start in his place. Tight end Brody Eldridge (ankle) and wide receiver Manny Johnson (dislocated elbow) both are expected to play.
Texas Tech is in pretty good shape in terms of injuries. The extra week gave Michael Crabtree time to rest and he told reporters earlier this week he's ready to play at 100 percent.
WEATHER CONDITIONS: It's an almost ideal football night at Owen Field, with one exception. A gusting south wind of up to 20 mph could play havoc with teams' passing strategies and the kicking game. But other than that, you couldn't ask for a better night in mid-November. Temperatures will start at kickoff in the mid-40s and should slide into the high-30s by the time the game finishes up.
