Lawrence Tynes booted the Giants into the Super Bowl again.

Tynes kicked a winning 31-yard field goal in sudden-death overtime and New York beat the San Francisco 49ers 20-17 in the NFC championship game Sunday night to reach its second Super Bowl in five seasons.

Eli Manning and the Giants (12-7) will face the New England Patriots in the Super Bowl on Feb. 5 in Indianapolis, just as they did when they won it in 2008.

Tynes also kicked the game-winning field goal in overtime at Green Bay in the 2008 NFC title game that put the Giants in the Super Bowl.

Devon Thomas put the Giants in position. He recovered his second fumble of the game after Jacquian Williams stripped the ball from fill-in return man Kyle Williams.

Las Vegas casinos say the New England Patriots are favorites to win the Super Bowl thanks to their national following, a decade of winning and the playoff success of quarterback Tom Brady and coach Bill Belichick.

Race and Sports Director Mike Colbert says the Patriots opened as three-point favorites over New York in odds posted Sunday night after the Giants beat San Francisco 20-17 in overtime in the NFC championship game.

New England beat the Baltimore Ravens 23-20 for the AFC title. Executive Race and Sports Director Jay Kornegay of the Las Vegas Hotel & Casino says an injury to Patriots tight end Rob Gronkowski is a factor that could swing the line up to one point.

Colbert says the 2008 Super Bowl rematch could break wagering records. The Patriots were 12-point favorites four years ago, but the Giants earned a 17-14 win.
