NFL stars have taken over Allianz Park in the build-up to their appearance at Wembley Stadium this weekend.

The Dallas Cowboys are using the stadium in Greenlands Lane, Hendon, which is the home of Saracens Rugby Club, as their training base ahead of their "away" match against the Jacksonville Jaguars, the designated home team, on Sunday.

It will be the third “regular season” NFL fixture to be played at Wembley this season, following the Miami Dolphins’ 38-14 victory over the Oakland Raiders, and the Detroit Lions’ last-minute 22-21 win against the Atlanta Falcons.
