Luck was apparently on the Cowboys' side.

Oklahoma State never led in regulation of the Fiesta Bowl, but the Big 12 champions didn't have to in pulling out a wild, 41-38, overtime victory over the Stanford Cardinal.

Andrew Luck was in line to end his stellar Stanford career with a second straight BCS bowl victory, but Jordan Williamson missed a 35-yard field goal on the final play of the fourth quarter.

The fourth-ranked Cardinal (11-2) failed to net any yards on the first possession of overtime, and Williamson was wide left for the third time of the night on the ensuing 43-yard attempt.

Colton Chelf appeared to catch the game-winning pass two plays later, but was pulled down at the one-foot line after hauling in Brandon Weeden's pass over the middle.

The replay reversal of Chelf's touchdown simply delayed the inevitable, as Quinn Sharp's 22-yard chip shot split the uprights to secure the first 12-win season in Oklahoma State (12-1) history.
