Norman, Okla. His ankle injured and his team defeated, Oklahoma running back Adrian Peterson had few words to explain what had just happened.
"Right now, I'm kind of shocked," he said.
He wasn't the only one.
TCU came up with its biggest upset in 45 years, stifling Peterson and beating No. 7 Oklahoma, 17-10, Saturday in the Sooners' first home loss since 2001 and first loss in September under coach Bob Stoops.
The Horned Frogs (1-0) came out with a plan to stop Peterson and make Oklahoma quarterback Paul Thompson beat them in his first career start. It worked.
While Peterson, the Heisman Trophy runner-up as a freshman last year, was held to 63 yards on 22 carries, TCU's Tye Gunn threw for 226 yards and a touchdown, and Robert Merrill scored the decisive touchdown on a two-yard run with 11:56.
The Horned Frogs took advantage of a fumble by Sooners backup quarterback Rhett Bomar. Bomar, who lost a quarterback competition to Thompson but did well enough to earn playing time, fumbled while retreating and trying to spin away from Jamison Newby. David Hawthorne picked up the ball at the TCU 17, and Merrill took an option pitch from Gunn and scored untouched four plays later. It was one of four turnovers -- including four fumbles -- by the Sooners.
"When we got the turnovers, their heads dropped," Hawthorne said. "It wasn't the same OU team that you saw last year."
The Sooners had one final chance with 2:05 left, but Thompson -- charged with replacing 2003 Heisman winner Jason White -- fumbled on a fourth-down play with 1:03 left, and the Horned Frogs recovered and ran out the clock.
Oklahoma fans quickly filed out while TCU players gathered by the band for the fight song amid the cheers of two sections of purple-clad Frogs fans.
"We were just trying to make a statement that, 'Hey, we're here,'" TCU offensive tackle Herbert Taylor said. "The Frogs come to play. We play hard."
The Horned Frogs last beat a team so highly ranked on Nov. 18, 1961, when they defeated No. 1 Texas 6-0. TCU also beat No. 7 Baylor 14-6 in 1960 and No. 2 Texas 14-9 in 1959.
Stoops, meanwhile, questioned his team's toughness and attitude.
"They came in here and beat us," he said, "and that is it."
