The New Orleans Saints shut out the Miami Dolphins in a 20-0 win in a defensive battle at Wembley.
After both teams were scoreless for the majority of the first half, the Saints finally put some points on the board with a Will Lutz field goal as time expired.
After the break, Drew Brees threw the first of two touchdowns on his 268-yard day to Michael Thomas on the Saints' opening possession.
Alvin Kamara caught the second TD in the fourth quarter, capping an impressive day for the rookie running back, as he hauled in 10 catches for 17 yards to go with five carries for 25.
It was expected to be a big homecoming for Dolphins back Jay Ajayi, who was born in London, but he was held to 46 yards on 12 carries as Miami become the first team ever to be held scoreless in an NFL International Series game.
The Dolphins finished with only 185 yards of offence on the day, its fewest since its last shutout, a 19-0 loss at Buffalo in December 2013.
New Orleans showed little more in a drab affair but picked up their second straight win to take their record to 2-2, while Miami fall to 1-2.
The pre-match interest surrounded how many players would kneel for the American anthem after over 20 did in the same stadium last weekend in protest at US president Donald Trump's inflammatory comments.
Only three would kneel - Miami's Julius Thomas, Michael Thomas and Kenny Stills - though the Saints had taken a collective knee before standing for the Star-Spangled Banner.
