Playing indoors at Chicago Stadium on a modified American football field, the Chicago Bears defeated the Portsmouth Spartans in the first playoff game of the National Football League.

Chicago Stadium was an indoor arena in Chicago from 1929 to 1995. When it was built, it was the largest indoor arena in the world with a maximum seating capacity of 26,000. It was the home of the National Hockey League's Chicago Blackhawks and the National Basketball Association's Chicago Bulls. It was used for numerous other sporting events, opening with a championship boxing match in March 1929. In sports, it gained the nickname, the "Madhouse on Madison", and a feature during events was the playing of the largest Barton pipe organ ever built. It also hosted five United States presidential nominating conventions, including for Franklin D. Roosevelt, and for his opponents in 1932 and 1944.

American football, referred to simply as football in the United States and Canada and also known as gridiron football, is a team sport played by two teams of eleven players on a rectangular field with goalposts at each end. The offense, the team with possession of the oval-shaped football, attempts to advance down the field by running with the ball or throwing it, while the defense, the team without possession of the ball, aims to stop the offense's advance and to take control of the ball for themselves. The offense must advance the ball at least ten yards in four downs or plays; if they fail, they turn over the football to the defense, but if they succeed, they are given a new set of four downs to continue the drive. Points are scored primarily by advancing the ball into the opposing team's end zone for a touchdown or kicking the ball through the opponent's goalposts for a field goal. The team with the most points at the end of the game wins.

The Chicago Bears are a professional American football team based in Chicago. The Bears compete in the National Football League (NFL) as a member of the National Football Conference (NFC) North division. They are one of two remaining franchises from the NFL founding in 1920, along with the Arizona Cardinals, which also began in Chicago. The Bears played home games at Wrigley Field on Chicago's North Side through the 1970 season; they have played since then at Soldier Field on the Near South Side, adjacent to Lake Michigan.
