The Challenge included the four fully qualified Division I (FCS) members of the WAC (Abilene Christian, Lamar, Sam Houston, and Stephen F. Austin) and Central Arkansas, Eastern Kentucky, and Jacksonville State of the ASUN Conference.

The winner of the challenge received an auto-bid to the NCAA Division I FCS football playoffs.
