AMES, Iowa (AP) -- Iowa State's turnaround was stunning. So was Iowa's, though for completely different reasons.
A week after struggling to beat Division I-AA Illinois State, Iowa State played inspired defense and capitalized on turnovers for all its points to shock No. 8 Iowa 23-3 on Saturday and end the Hawkeyes' nine-game winning streak.
Iowa State (2-0) frustrated Iowa (1-1) throughout the steamy afternoon, recovering three fumbles and intercepting two passes, one of which LaMarcus Hicks returned 28 yards for a touchdown.
Iowa had scored with ease in a 56-0 rout of Ball State in its opener, but the Hawkeyes were so inept offensively in this one that they never got closer to the end zone than the Iowa State 26.
"We had to be one of the most improved teams in the country from week one to week two if we were going to have a chance," Iowa State coach Dan McCarney said. "That's the way we played today."
It was Iowa State's first victory over a Top 10 team under McCarney, the coach since 1995, and the first for the school since a 19-10 win over No. 7 Nebraska in 1992.
"It's been a long time coming," McCarney said. "It's about time, I guess."
Iowa got 140 yards rushing on 18 carries from Albert Young but had little else going. The Hawkeyes' lone score was a 44-yard field goal by Kyle Schlicher in the third quarter.
Even worse, Iowa lost quarterback Drew Tate with an apparent concussion midway through the second quarter. He was expected to return for next Saturday's game with Northern Iowa, coach Kirk Ferentz said.
"I think he's going to be fine, but obviously he couldn't have come back in the second half," Ferentz said. "You don't put a guy back in when he gets dinged like that."
Iowa State was hardly overwhelming on offense, managing a modest 323 total yards. But it wasn't necessary with the way Iowa self-destructed.
"This is about as good a feeling as you can have playing football," said ISU quarterback Bret Meyer, who threw for one touchdown and set up another with a long completion. "This game is what it is and if it helps us gain respect, that's good. I hope people start realizing we can play football, too."
While the most anticipated game in the in-state rivalry in years didn't live up to the hype, it drew a crowd of 54,290 -- the largest at Iowa State's Jack Trice Stadium since it was reconfigured in 1996 -- in 90-degree heat.
Iowa State's students were so eager that hundreds were in their seats two hours before kickoff, spurning all the tailgating parties in the parking lots. Thousands stormed the field after the game.
"I looked into the stands and saw a bunch of former Cyclones and for us to win with them there, it was just awesome," Iowa State safety Nik Moser said.
Trailing 16-3, Iowa had a chance to make it interesting, driving to a first down at the Iowa State 30 midway through the fourth quarter. Three plays later, though, Scott Chandler fumbled after catching a pass. Hicks recovered at the Iowa 20.
With black- and gold-clad Iowa fans streaming out of the stadium, Iowa State drove 80 yards in nine plays for the clinching touchdown. Meyer's 40-yard pass to Todd Blythe put the ball at the 2, and Ryan Kock bulled into the end zone on the next play.
"I thought we learned our lesson last year at Michigan," said Iowa receiver Ed Hinkel, recalling a turnover-filled game with the Wolverines that had been the Hawkeyes' last loss. "We can't turn the ball over and expect to win. We're not that good. Our margin of
error is not that high."
Tate, the Big Ten's preseason offensive player of the year, was hurt tackling Steve Paris after throwing an interception with Iowa trailing 9-0. He first was examined on the sideline before walking to the locker room and watching the second half in sweat clothes.
Jason Manson, a junior who has played little in his career, replaced Tate. On his third play, he fired a pass to Hinkel that Iowa State's Adam Carper tipped. The ball went right to Hicks playing deep and he ran untouched down the left sideline, giving the Cyclones a 16-0 lead.
"It was great underneath coverage," Hicks said. "Once I saw the tip, I went for it and got it. I saw the sideline open up and I took it."
Paris' interception and 18-yard return to the Iowa 46 had set up Tony Yelk's 29-yard field goal that made it 9-0.
Iowa State failed to capitalize on Iowa's first turnover, but the next time the Hawkeyes coughed it up, the Cyclones converted.
Brian Ferentz, the coach's son, snapped the ball over Tate's head in shotgun formation. Tate and Young both hesitated as they closed in on the ball, as if thinking the other would jump on it, and Iowa State's Jason Berryman swooped in to recover it at the Iowa 12 with 7:15 left in the first quarter.
After Meyer was stopped for no gain, he hit Austin Flynn on a crossing pattern and the former quarterback took into the end zone.
