Jeff Woody scored on a 4-yard run in the second overtime and Iowa State stunned second-ranked Oklahoma State 37-31 on Friday night, derailing the Cowboys' national title hopes.
The Cyclones (6-4, 3-4 Big 12) overcame a 17-point deficit to beat the Cowboys (10-1, 7-1 Big 12), who were just a win away from a showdown with rival Oklahoma for a likely spot in the BCS title game.
Oklahoma State quarterback Brandon Weeden's first pass in the second overtime was intercepted by Leonard Johnson. Woody then bullied his way into the end zone to give the Cyclones their first victory over a top-five opponent in school history.
Weeden threw for 476 yards, but had three interceptions as the Cowboys turned it over five times.
