The Leathernecks (4-2, 3-0 Missouri Valley Conference) led all the way, taking a 7-0 first-quarter lead when Aaron Diggs snagged an interception and ran 95 yards to score. Knuffman's final field goal was from 23 yards.
Northern Iowa (2-4, 0-3) rallied with a pair of TDs after halftime - Deiondre' Hall scoring on a 32-yard interception return, and Aaron Bailey punching across from the 5. Bailey's TD pulled the Panthers to 21-19 after a two-point conversion pass failed with 6:35 remaining. Hall's second pick this season makes four career interceptions, breaking the school record.
