London will host four regular season NFL games for the first time in 2017.
The move to four games is significant because it represents half of a home schedule for a regular season, as the league continues to build towards a potential expansion franchise in the capital.
The teams and the venues for the four games of the 2017 London Series will be confirmed on Tuesday, although we already know the Miami Dolphins will return to London as the designated home team against the New Orleans Saints, while the Jacksonville Jaguars are also committed to 'hosting' a game.
The NFL has played three games in London to sellout crowds in each season since 2014, having first played a regular season game at Wembley in October 2007.
NFL commissioner Roger Goodell, said: "We continue to be incredibly excited by the passion and love for the NFL shown by our millions of UK fans."
London mayor Sadiq Khan added: "London staging a fourth NFL game is fantastic news - not only for the millions of sports fans who get to enjoy our iconic stadiums - but also because it confirms our status as the go-to choice for hosting the world's biggest sporting events.
"London is the international home of the NFL and staging the equivalent of what would be half an American football team's home games in the city is a huge step towards my ambition of bringing a franchise to the capital.
"I am really excited to welcome more NFL teams to London next year, as well as thousands of American football fans from around the globe, showing that London is open to the very best sporting events and the world's greatest athletes."
