Boise State will look to take down Penn State in the Fiesta Bowl, which will serve as a College Football Playoff quarterfinal. The Broncos are the first non-power conference team to make the CFP in the expanded 12-team field.

Fans will tune into Tuesday’s game looking to see how Boise State performs on college football’s biggest stage. But what you may not know is that the Broncos are no stranger to upsetting Goliath as the underdog. Back in 2007, Boise State delivered one of college football’s most incredible upsets over Oklahoma in the Fiesta Bowl.

The game is considered to be one of the greatest in college football history. It featured a fourth-quarter comeback, 37 points scored in the last 1:26 of regulation and overtime, three iconic trick plays and one on-field marriage proposal.

“We’re seeing a College Football Playoff system that’s been implemented now, and if you can target one game that probably shifted the old school thought, it was probably that game,” Boise State’s 2007 Fiesta Bowl quarterback Jared Zabransky said. “I truly believe that our team played a huge part in the transformation of Division I-A football.”

Let’s relive how Boise State stunned Oklahoma in the 2007 Fiesta Bowl, a game etched in college football history.
