The Broncos (4-4, 3-2) were on defense first in the extra period, and when John Rachuna missed on a 43-yard attempt, they needed only to score to win. Five Brandon West rushes put the ball on the Bulls 10 and Potter's kick ended the game. The Bulls (3-5, 1-3) had forced overtime on the final play of regulation on A.J. Principe's 28-yard field goal.
West ran for 133 yards and two touchdowns on 27 carries, and Tim Hiller threw for 350 yards and two touchdowns for Western Michigan. West's second TD put the Broncos ahead 31-28 with 1:58 left in the fourth quarter after Ike Nduka's third touchdown, a 56-yard run, had given the Bulls a 28-24 lead with 5:16 to play. Nduka finished with 172 yards rushing for Buffalo.
