One of the most controversial plays in NFL history occurred during this game. With time winding down, Bronko Nagurski threw a forward pass to Bill Hewitt, who lateraled to Billy Karr, who scored a touchdown. This play led to the creation of the "Bronko Nagurski Rule," which allowed forward passes to be thrown from anywhere behind the line of scrimmage.

The game was a thrilling back-and-forth affair, featuring six lead changes. In the end, the Chicago Bears defeated the New York Giants 23-21, with Red Grange's crucial tackle preserving the victory.

This historic game not only determined a champion but also led to significant rule changes, including the division of the league into two divisions and the movement of the hash marks and goalposts. These changes helped to modernize the game and make it more exciting for fans.
