In 1932, the season ended with the Chicago Bears (6–1–6) and the Portsmouth Spartans (6–1–4) tied for first in the league standings. At the time, teams were ranked on a single table and the team with the highest winning percentage (not including ties, which were not counted towards the standings) at the end of the season was declared the champion; the only tiebreaker was that in the event of a tie, if two teams played twice in a season, the result of the second game determined the title (the source of the 1921 controversy). This method had been used since the league's creation in 1920, but no situation had been encountered where two teams were tied for first. The league quickly determined that a playoff game between Chicago and Portsmouth was needed to decide the league's champion. The teams were originally scheduled to play the playoff game, officially a regular season game that would count towards the regular season standings, at Wrigley Field in Chicago, but a combination of heavy snow and extreme cold forced the game to be moved indoors to Chicago Stadium, which did not have a regulation-size football field. Playing with altered rules to accommodate the smaller playing field, the Bears won the game 9–0 and thus won the championship. Fan interest in the de facto championship game led the NFL, beginning in 1933, to split into two divisions with a championship game to be played between the division champions. The 1934 season also marked the first of 12 seasons in which African Americans were absent from the league. The de facto ban was rescinded in 1946, following public pressure and coinciding with the removal of a similar ban in Major League Baseball.
