The NFL has staged regular season games in London since 2007.

The 2013 season is the first in which Wembley has staged two games – the further expansion to three next season is regarded by some observers as a hint that there could ultimately be a team based in London.

Season tickets for the 2014 games will go on sale on 3 December to those who attended both of this season’s clashes.

The Cowboys have never played a competitive match in the UK and are joined in making their first International Series match by Detroit, Atlanta and Oakland.
