IOWA CITY, Iowa -- Penn State's quest for a national title has ended.
A team that looked unflappable all season struggled down the stretch, giving Iowa a chance to rally for a monumental upset. The Hawkeyes erased a 9-point fourth-quarter deficit and won the game, 24-23, on a 31-yard Daniel Murray field goal with two seconds left.
Murray converted the winner with the wind at his back. Freshman Trent Mossbrucker had handled most of the kicks for Iowa, including the extra points Saturday, but with the game on the line, the Hawkeyes went with Murray, a more experienced player who kicked last year.
No. 3 Penn State made uncharactistic mistakes in the second half, dropping several passes and making questionable decisions. Junior quarterback Daryll Clark, who had displayed remarkable poise for most of the season, threw an interception that led to the decisive scoring drive. Iowa quarterback Ricky Stanzi rebounded from two second-half turnovers and led the Hawkeyes downfield in the final minutes, going 57 yards in 15 plays.
The crowd is storming the field. I'll be back later with more updates.
