The 1931 NFL season was the 12th regular season of the National Football League. The league decreased to 10 teams due to financial hardships caused by the Great Depression: while the Cleveland Indians joined as an expansion team and the league lost the Minneapolis Red Jackets and the Newark Tornadoes, the Frankford Yellow Jackets folded midway through the season.
Meanwhile, the Green Bay Packers were named the NFL champions for the third consecutive time after major controversy when they decided to cancel a season-ending game against Portsmouth, which was alleged to have been in order to preserve their first-place finish: major rule changes were made in the scheduling of games to prevent any repeat of this incident.[1]
