London's NFL fans were treated to a rare spectacle on Sunday as the Washington Redskins and Cincinnati Bengals played to a tie.
Dustin Hopkins missed a 34-yard field goal attempt which would have won the game with 2:09 left in the extra period and the game finished 27-27 - only the fifth tie in the NFL since 2012 but the second in the space of as many weeks.
After Hopkins missed, the Bengals turned the ball over as quarterback Andy Dalton fumbled, but Washington could not take advantage as the clock ran out on the first overtime period to be played in London.
Hopkins was not the only kicker with a costly miss in the game, however, as Cincinnati's Mike Nugent missed a routine point after touchdown kick in the third quarter which would have changed everything.
It was Hopkins who forced overtime at Wembley with a 40-yard field goal late in regulation after Jeremy Hill's one-yard touchdown run put Cincinnati on top, 27-24, with 6:58 to go.
Last weekend, the Arizona Cardinals and Seattle Seahawks both missed field goals in overtime as they played to a 6-6 tie, but it remains a highly unusual result in the NFL.
Peyton Manning has announced the end of his 18-year National Football League career.
The 39-year-old quarterback, a five-time winner of the league's Most Valuable Player award, guided the Denver Broncos to victory in Super Bowl 50 last month when they beat the Carolina Panthers 24-10.
"When you look at everything Peyton has accomplished as a player and person, it's easy to see how fortunate we've been to have him on our team," Broncos executive vice-president of football operations and general manager John Elway told the team's website.
NFL commissioner Roger Goodell has said it is a "realistic possibility" that there will be a UK-based franchise if the sport continues to grow in Britain.
For the third successive year, the 2016 season will see three games hosted in the capital, with Twickenham joining Wembley in staging International Series fixtures outside of the United States.
Speaking at a press conference in San Francisco ahead of Sunday's Super Bowl 50, Goodell said he expects more games to be taken to London and did not rule out the possibility of a team one day being based on British soil.
"We are considering playing more games in the UK, it's a balancing act with our schedule," he said.
"As you know, we're playing in two stadiums next year and that gives us a little bit more flexibility of how to do that. I believe the future will see more games in the UK.
"As far as a franchise, let's continue to grow, to see that excitement, enthusiasm, passion and support continue to develop. If it does, I think that's a realistic possibility."

Former British Olympian Lawrence Okoye has signed for the Arizona Cardinals after being waived by NFL rivals the San Francisco 49ers.
Okoye, who still holds the British record for the discus, was let go by San Francisco last week after two seasons trying to establish himself in American football having swapped the track for the gridiron following the 2012 Olympics.
Franchises finalised their 53-man rosters over the weekend but Okoye revealed he has been given a shot by the Cardinals, who, like the Niners, play in the NFC West, and will wind up on their practice squad where he can continue his NFL education.

Jurors on the murder trial of former New England Patriots player Aaron Hernandez can watch this weekend's Super Bowl - but must walk away if he is mentioned.
The judge at Bristol County Superior Court, Susan Garsh, told the jury they could watch the game but must take precautions to avoid being exposed to information about Hernandez. The Patriots take on the Seattle Seahawks in the showpiece event on Sunday.
Hernandez is charged over the shooting death of semi-professional football player Odin Lloyd in 2013. The trial began on Thursday with opening statements.
Twenty-five-year-old Hernandez, who caught quarterback Tom Brady's last Super Bowl touchdown pass in the Patriots' 2012 loss to the New York Giants, had a $40 million contract with the New England team when he was arrested.
