Dates for the games will be set at a later time.
"Our fans in the UK continue to demonstrate their passion for more football," Goodell said in a statement released by the league. "Next year for the first time we will play three regular-season games in London. We have scheduled three attractive games with four teams playing in their first International Series game. The growing enthusiasm for the NFL internationally is exciting and we look forward to continuing to respond to this interest in our game."
