(Stats Perform) - The fourth annual Big Sky-MVFC Challenge Series involves six games this year, the fewest since its inception in 2017.

The MVFC has won each of the first three years - 5-3 in both 2017 and '18 and 6-3 last year - in a series that was created to publicize matchups between two of the leading FCS conferences.

This year, MVFC power Northern Iowa is the only school playing in multiple games. Big Sky program Portland State is involved for the first time, while North Dakota will represent the MVFC for the first time after playing twice as a Big Sky member in 2017.
