A double doink with the last kick of the game saw the New Orleans Saints fall to a 28-25 defeat against the Minnesota Vikings in London.
The Saints defence kept Vikings quarterback Kirk Cousins' impact on the game limited for the majority, before crucial plays in the fourth quarter saw the game turn on its head on numerous occasions.
Justin Jefferson punched the Vikings in front, but the extra point was missed, with the Saints then stopped by the Vikings defense, though Wil Lutz struck a field goal from 60 yards to tie the game.
The Vikings pulled ahead from the following drive with Joseph kicking a fifth field goal of the game, but there was still time for more drama, Lutz striking the left upright and the crossbar with a 61-yard attempt with the final kick of the game.
The contest was tied at the two-minute warning before half-time, Chris Olave's first career touchdown cancelling out Alexander Mattison's opener on the first drive, and the Vikings pushed ahead with three field goals, including two in the final 70 seconds of the half.
The Saints finally burst into action with a 78-yard drive down the field in the third quarter, the highlight being Andy Dalton's 33-yard throw to Marquez Callaway, and Latavius Murray punched in from a yard to bring the game to within a score.
That sparked new life into the Saints, despite another Vikings field goal, Taysom Hill putting the designated home side ahead before New Orleans moved three ahead with a successful two-point conversion, though Jefferson's three-yard reception put the Vikings ahead again.
A 60-yard field goal from Lutz tied the game at the start of the two-minute warning, but Joseph stepped up again to deliver with his kick.
The Saints then faced defeat in agonising fashion as the last-gasp effort from Lutz struck the upright and bounced off the crossbar to decide the game as the Saints fell to 1-3 for the season.
