NFL fans in London were forced to battle through enormous queues and face severe delays following an issue with their OnePass ticketing app at the Tottenham Hotspur Stadium on Sunday afternoon.
The American powerhouse sport has made the north London stadium its home in the UK, hosting a number of games at the ground throughout the season.
Kicking off the run of ties in London is a meeting between the Cleveland Browns and the Minnesota Vikings.
Sunday marks the first time that the two sides have faced one another in capital in nearly 10 years, with their last meeting coming in 2017 at Twickenham.
