The 2005 season was the Arizona Cardinals' 86th in the National Football League (NFL), their 107th overall and their 18th in Arizona. The team was unable to improve upon their 6–10 record from the previous season, and failed to make the playoffs for the seventh year in a row. The October 2 game was the first regular season game to be played outside the United States, and was known as NFL Futbol Americano. The game was a Cardinals home game, and the Cardinals defeated their division rivals, the San Francisco 49ers, 31–14.
