With the biggest win in school history less than 3 yards away, North Dakota State went for two and failed.
The Bison earned the ball back though — and they finished off the program's signature victory by running the ball right at Iowa.
Cam Pedersen kicked a 37-yard field as time expired and North Dakota State, of the FCS, rallied to beat No. 13 Iowa 23-21 on Saturday for its sixth straight win over an FBS opponent.
The Bison went for a 2-point conversion down 21-20 with 3:41 left, but couldn't punch it in. North Dakota State's defense then held, and quarterback Easton Stick's 29-yard run put the Bison in position for the biggest win in school history.
