Peterson leads the Vikings to win in London.
The Minnesota Vikings sealed a 34-27 win over the Pittsburgh Steelers at Wembley on Sunday night, and as a result rescued their season for the time being.
With both teams having lost their opening three games of the season, a defeat at Wembley would have been catastrophic for their ambitions of reaching the playoffs.
It would be the Steelers who fell to 0-4 for the first time since 1968, and history tells us that only one team has ever dug itself out of that hole to make the playoffs, with the San Diego Chargers achieving the feat back in 1992.
Matt Cassel started in place of the injured Christian Ponder for Minnesota, but it was Greg Jennings and Adrian Peterson that led the Vikings to victory with two touchdowns apiece.
In arguably the most entertaining NFL International Series game that has been held in London, Jennings provided the biggest highlight with his 70-yard catch-and-run while Peterson delighted the home crowd with a 60-yard touchdown in the second quarter.
However, the Vikings were made to deal with some nervy moments as the game came to a conclusion, with Ben Roethlisberger being stripped of the ball by Everson Griffen on the 6-yard line with 19 seconds to go.
Kevin Williams recovered the fumble and Minnesota went on to seal a much-needed win, which in contrast leaves the Steelers in all kinds of trouble for the remainder of the regular season.
Cassel finished 16 of 25 for 248 yards and two touchdowns with no turnovers, but despite his impressive performance, coach Leslie Frazier insisted that Ponder will remain the franchise quarterback.
