Lubbock, Texas ? Texas Tech quarterback Seth Doege is hoping for a memory lapse when the 19th-ranked Red Raiders take the field tonight against Iowa State.

He figures that’s the best way for his team to avoid a letdown after last week’s 41-38 upset win at third-ranked Oklahoma.

“We’ve got to forget about this one. It’s over. It was awesome,” said Doege, the nation’s leading passer who’s averaging about 372 yards per game. “If you want this one to continue to be special . . . then you’ve got to win the next one.”

One memory still vivid around here is the Red Raiders’ 52-38 loss last year in Ames, when turnovers and a late onside kick backfired for an ISU touchdown.

Despite not having played, Doege remembers that Iowa State “gave it to us pretty good.”

Texas Tech coach Tommy Tuberville called the loss in Ames a “big disappointment.” His team started slow, falling behind Iowa State 24-0.

“But they outplayed us,” Tuberville said. “Outcoached us, outplayed us, and it wasn’t a very good plane trip on the way home. But each year you get another shot, and this year our shot is here.”

The game for the Red Raiders (5-2, 2-2 Big 12) comes a week after they stunned the Sooners, who were riding a home win streak of 39 games. Doege threw for four touchdowns and ran for another. The win got Texas Tech back into the poll for the first time since the end of the 2009 season.

The Red Raiders would be bowl eligible for a 19th straight year with a win tonight.

“The quarterback was unbelievably accurate with his throws,” said Iowa State coach Paul Rhoads, who was Tuberville’s defensive coordinator at Auburn in 2008. The win at OU “confirmed what we already know about this league. Every week you’re going to be challenged to play great football if you’re going to have an opportunity to win.”

The Cyclones (3-4, 0-4) are desperate for a conference win and are pinning their hopes on Jared Barnett, a red-shirt freshman from Garland who’ll be making his first start at quarterback. He replaces Steele Jantz, a junior who crafted a few come-from-behind wins earlier this year.
