The Cincinnati Bengals and the Washington Redskins played out a 27-27 tie in a thrilling contest at Wembley Stadium.
The game - the 17th in the NFL's International Series - went to overtime after finishing level in regulation time.
Dustin Hopkins missed a 34-yard field goal in the extended period that would have won the game for the Redskins, but both teams will return to the United States with a messy tie on their records.

Washington fought back from deficits of 20-10 and 27-24 to extend the game as London staged its first ever overtime period.
It's these sorts of contests that will certainly keep British NFL fans coming back for more.

Here are eight things you missed at Wembley Stadium.
Domata Peko embraced Britain
It’s pretty common to see NFL players wearing customised cleats. In the warm-up to the Minnesota Vikings’ game against the Philadelphia Eagles last Sunday, Jerick McKinnon donned a pair that read ‘RIP Harambe’.
It was cool to see Bengals’ defensive tackle Domata Peko embracing the International Series by wearing Union Jack inspired cleats.
Great support for the Bengals
Last week’s contest between the Los Angeles Rams and the New York Giants at Twickenham went down as a Rams’ home game, but it sure didn’t feel like it.
There were probably more Odell Beckham Jr. jerseys inside the stadium than there were entire LA Rams shirts.
But if the Bengals feared that the Wembley Stadium crowd wouldn't entirely have their back, they were in for a welcome surprise.
The atmosphere when the Bengals players entered the field was as vibrant as it was negative when Kirk Cousins was facing a third down.
Rob Kelley has a brilliant nickname
Redskins’ rookie running back Rob Kelley, scorer of their first touchdown, is nicknamed ‘Fat Rob’.
“My senior year, my running backs coach brought me a backpack with ‘Fat Rob’ [inscribed on it], a nickname I actually earned in the offseason eating a lot of food,” Kelley explained in August, via the Washington Post.
If he continues to find the pay dirt, he’ll soon have a new nickname.
Footballers in attendance
Paul Pogba travelled all the way from Manchester to attend today’s game. He was spotted on the sideline speaking with Arsenal legend Thierry Henry.
Hector Bellerin and Adebayo Akinfenwa also swapped football for the American version.
AJ Green won the battle vs Josh Norman
Get the popcorn out, they said. Norman versus Green will be a thriller.
As it turned out, we had to wait until the second half before the contest between the Redskins’ cornerback and Bengals’ wide receiver started to deliver.
In the first half, Green was held to just one reception for 10 yards.
Norman showed just why Washington was willing to sign him to a five-year, $75 million contract by eliminating Green in the first two quarters.
However, in the final quarter, Green came up huge with a 40-yard grab on Norman - who was guilty of pass interference - that set up Jeremy Hill's touchdown.
Norman dropped two interceptions and had a brilliant pass breakup in the third quarter. He didn't have a terrible game; simply, AJ Green is a monster.
One hundred International Series touchdowns
Seventeen games, 100 touchdowns.
Jamison Crowder had the honour of scoring the 100th International Series touchdown, catching a pass from Cousins and finding the end zone for a 33-yard score.
Here’s to one hundred more.
What is it with London and terrible interceptions?
Andy Dalton threw an ill-advised interception at the beginning of the fourth quarter that ended a promising Bengals drive.
There must be something in the London air, for LA Rams QB Case Keenum threw a dumb interception last week against the Giants at Twickenham.
Cincinnati led 20-17 at the time, and were on the Redskins’ 20-yard line. Ill-advised might be an understatement.
Britain loves American football. A lot
