In the Eastern race, the Eagles beat Washington 45–0 in Week Five to take a 1/2 game lead. When the 6–1–1 Eagles met the 6–2 Skins again in Week Ten, Washington lost a must-win game, 42–21.
The other race was all Chicago, as the Cardinals and Bears both had records of 10–1 going into the final week. A record crowd of 51,283 packed Wrigley Field on December 12 to watch. The Bears took a 21–10 lead, on George Gulyanic's as the fourth quarter began. Charley Trippi's touchdown cut the margin to 21–17, but the Bears had the ball and time on their side. The turning point came when the Cards' Vince Banonis picked off a pass from Johnny Lujack, and ran the ball back to the Bears' 19, and Elmer Angsman scored the winning touchdown three plays later for the Western Division title and the trip to the championship.
