WHAT'S AT STAKE

Marshall already has qualified for the Dec. 6 conference championship game. That gives the Thundering Herd two chances to further impress the College Football Playoff committee before it picks a team from outside the five major conferences for a guaranteed spot in the New Year's bowls. Marshall is one place behind Boise State (No. 23 CFP). Western Kentucky is looking to solidify its resume for a possible bowl bid.
