According to NFL.com, two regular season games will appear at Wembley Stadium, London, UK. The NFL is working closely with the London city consul to make it a satisfying experience for Americans in UK at the time or curious Londoners. The future of NFL Europa is looking good for German sports so maybe that success can come to London for two games. It will be broadcasted in UK and Fox Sports Net.
The NFL staged its first regular-season game outside of the United States in 2005 when 103,467 people saw the Arizona Cardinals play the San Francisco 49ers in Mexico City on October 2 -- the largest crowd for a regular-season game in NFL history.
Maybe if this works, football can have world-wide fanfare so it's not only North America that plays it.
