9. Estadio Azteca
The NFL first played outside of the U.S. in the 1950s when it staged a series of games between its franchises and Canadian Football League teams north of the border. In 1976, the NFL ventured outside of North America for the first time as the Cardinals and Chargers played an exhibition game in Tokyo.
But it wasn't until 2005 when the first NFL regular-season game was played outside of American soil. Though soccer will always be Mexico’s first love, on Oct. 2, 2005, a record crowd of 103,467 enthusiastically embraced futbol americano at Mexico City's historic Estadio Azteca, normally the home field of Mexico's national team and a place where the U.S. has never won a single match.
But the Arizona Cardinals did, with kicking a prominent aspect in their victory as Neil Rackers hit six field goals in the Cards' 31-14 victory over the San Francisco 49ers.
