^a The game, won by Dillon 22-21 on the field, was subsequently forfeited because quarterback "Voodoo" Tatum was ruled ineligible for not having satisfied residency requirements.

^b Final score not revealed, though a TV newscast indicates the game was a lopsided win with Brian "Smash" Williams scoring 3 touchdowns.

^c Final score not shown, but Dillon scored a touchdown with about five minutes left in scoreless game.

^d The referees at Dunston were allowing the home team to commit infractions such as facemasks, late hits, and pass interference without penalties. When Dillon scored in the fourth quarter to take a commanding 40–24 lead, a Cardinal hit Smash after he scored the touchdown, again with no penalty call. Riggins rushed to Smash's defense, and a melee ensued before the extra point could be attempted. The game was called at that point, and Dillon was awarded the victory.

^e The game was played at a makeshift field due to a toxic train car derailment.
