The U.S. National Football League will stage two matches in a season in the UK for the first time.
Wembley hosted the first regular-season NFL fixture in Europe in 2007 and has held games annually since.
It will again be the venue in September next year, when the Minnesota Vikings play the Pittsburgh Steelers.
This is in addition to the previously announced game at Wembley set for October 27 when the Jacksonville Jaguars face the San Francisco 49ers.
"Since we started playing regular-season games in London five years ago, we have heard very clearly from our UK fans – they want more football," said NFL commissioner Roger Goodell.
Earlier this year, the Jacksonville Jaguars opened a new chapter for the NFL in the UK, making a multi-year commitment to International Series games in London.
They will play one regular-season home game in the UK in 2013, 2014, 2015 and 2016, all at Wembley.
