All players are required to wear numerals on their jerseys whose color must be in sharp contrast with the jersey color. The numbers on the front must be at least 6 inches (150 mm) while the ones on the back must be at least 8 inches (200 mm).
If a kickoff goes out of bounds, the ball is put in play either on the opponent's 35-yard line or 10 yards from the spot where it crossed the sideline.
The penalty for an illegal forward pass that is thrown beyond the line of scrimmage is a loss of down and five yards from the spot of the foul.
Midway through the NFL's 11-game season, the Bears were unbeaten (5–0) in the Western Division, while the Giants were leaders in the Eastern (4–1), and they played to a 3–3 tie. The Giants and Bears continued to stay in the lead in their divisions, and the Bears clinched a spot in the title game with its 13–0 win over Detroit. On December 5, the final game of the season had Washington (7–3 and .700) traveling to New York (6–2–2 and .750). A win or a tie would have given the Giants the Eastern title; the Redskins triumphed, 49–14, and got the division crown and the trip to face Chicago in the 1937 championship game.
