San Francisco 17 NY Giants 20
The Giants won a nailbiting NFC Championship game in overtime in San Francisco thanks to a 31-yard field goal.
They will now face New England in Indianapolis at Super Bowl XLVI on February 5 after the Patriots clinched their place earlier in the evening with an equally tight 23-20 victory at home to Baltimore.
New England fans were also left on the edge of their seats after Baltimore spurned the chance to take the game into overtime when kicker Billy Cundiff MISSED a short-range field goal with 11 seconds left.
The big match-up is a repeat of the title game in 2008, when hot favourites New England were denied a perfect season by a shock touchdown in the final minute as the Giants recorded a famous 17-14 win.
Quarterback Manning, who was the Super Bowl MVP four years ago, made sure the New Yorkers would get another chance at glory by throwing two touchown passes and then guiding the team to the clinching field goal by their Scots-born kicker.
A heavyweight defensive battle was played in almost constant torrential rain and neither team was able to make much impression for long periods.
But the 49ers
