The NFL is to consider staging a second game in the UK every season following its success in bringing teams to play regular season matches in London.
Wembley Stadium has hosted two games so far, with a third set for 25 October.
League commissioner Roger Goodell said: "The fan reaction we have had in London has been extraordinary. We would like to feed that passion.
"There have been discussions [about] a second game in another UK market - that's something that we'll evaluate.
The NFL first staged a regular-season game in London in 2007, when the New York Giants beat the Miami Dolphins 13-10.
Last year, the New Orleans Saints overcame the San Diego Chargers 37-32.
Both games were sell-outs, and fans quickly snapped up tickets for this season's game between the New England Patriots and Tampa Bay Buccaneers.
Goodell said there are no plans to play a Super Bowl in London, but added a second regular-season game was drawing support from league owners.
"I think the teams that have gone over [to London] have had a great experience," he said.
"We've been able to build on that, and I think teams recognise it's an honour and a privilege to play there. And it can be done without impacting them negatively."
However, some players have been critical of the overseas game because of the extensive travel involved in the middle of the season.
One team also loses a home fixture in the arrangement.
"The negative is taking the home game away from the fans," Goodell admitted.
"It's another reason why potentially restructuring the season and changing two pre-season (games) into regular-season (games) can be something that is beneficial to the fans." http://news.bbc.co.uk/sport2/hi/other_sports/american_football/8047096.stm
