Brock Jensen backed into the end zone for the go-ahead touchdown with 28 seconds left, and North Dakota State upset defending Big 12 champion Kansas State, 24-21, Friday night in Manhattan, Kan.
The senior quarterback led the Bison on an 18-play, 80-yard march that ate up 8½ minutes, helping them convert four third downs along the way, and left the Wildcats with virtually no time left to set up a tying field-goal try.
Jensen threw for 165 yards and two touchdowns for Bison, the two-time defending FCS national champions who have beaten Colorado State, Minnesota, and Kansas in the last three years.
Sam Ojuri had 10 carries for 127 yards, and John Crockett also ran for 50 yards for the Bison. Full story for BostonGlobe.com subscribers.
