The first ever playoff game was played in a hockey rink; The field was only 80 yards

In 1932 the Chicago Bears and Portsmouth Spartans (later the Detroit Lions) played in the first ever playoff game in NFL history. It just happened to be for the NFL title.

The game was to be played at Wrigley Field in Chicago. The Bears came in with a 6-1-6 record and the Spartans had a 6-1-4 record.

However, because of extremely cold weather, the game was played inside the Blackhawks hockey arena, Chicago Stadium.

Specials rules were made for the game. The dirt field was only 80 yards and 10 yards narrower than a regular field. The ball was automatically moved 20 yards back every time a team crossed the 50-yard line.

Could you imagine the NFL using a Hockey rink now-a-days?  That would be like Arena Football….
