San Francisco 49ers tight end Vernon Davis (85) runs from New Orleans Saints free safety Malcolm Jenkins (27) and strong safety Roman Harper (41) during the fourth quarter of an NFL divisional playoff football game Saturday, Jan. 14, 2012, in San Francisco.

SANTA CLARA, Calif. — Any cold-weather garments Vernon Davis owns are getting tossed aside as quickly as he changed San Francisco's playoff fortunes with a game-winning touchdown catch against the favored Saints.

Instead of gearing up — literally speaking — for a trip to frigid Green Bay, the 49ers (14-3) get to stay right at home in the much-warmer Bay Area to host the New York Giants in the franchise's first NFC championship game since the 1997 season.

The NFC West champion Niners already beat New York 27-20 at Candlestick Park in November, and both teams have come far since Justin Smith batted down Eli Manning's last-ditch pass to seal it in the waning moments.

The Giants stunned the defending Super Bowl champion Packers on Sunday to give San Francisco the home field.
