Ames, IA – Oklahoma State's national championship hopes ranked Cowboys, 37-31, to shake up college football's landscape.
A heavy favorite, the Cowboys (10-1) had a chance to pull out the win in regulation, but Quinn Sharp narrowly missed a 37-yard field goal wide right.
After trading touchdowns in the first overtime, Heisman Trophy-hopeful Brandon Weeden's pass intended for Justin Blackmon was tipped into the hands of Ter'Ran Benton for an interception.
Jeff Woody then barreled into the end zone from four yards out to secure the unlikely victory, the Cyclones' (6-4) first in 19 games against teams ranked No. 1 or No. 2.
The outcome has severe repercussions on the BCS standings, as teams ranked No. 2 through 10 all have one loss.
