Seattle, WA (SportsNetwork.com) - Richard Sherman tipped Colin Kaepernick's pass and then celebrated when his teammate came away with the pick. Moments later, he screamed into a TV camera that he was the best cornerback in the NFL.

One thing's for sure: The Seattle Seahawks, in front of their noisy, proud fans, proved they were the best team in the NFC.

Russell Wilson threw a 35-yard touchdown pass to Jermaine Kearse in the fourth quarter and the Seahawks scored 13 unanswered points Sunday to beat the San Francisco 49ers 23-17 in the NFC Championship Game.

After Sherman tipped a pass intended for Michael Crabtree in the back-right corner of the end zone, linebacker Malcolm Smith picked it off to halt a 49ers drive in the final minute, sealing Seattle's second Super Bowl trip.

The Seahawks will face Peyton Manning and the Denver Broncos on Sunday, Feb. 2, at MetLife Stadium in East Rutherford, N.J. Denver beat New England 26-16 in the AFC title game Sunday.

Wilson passed for 215 yards, Marshawn Lynch rushed for 109 with a 40-yard touchdown run and top-seeded Seattle erased deficits of 10-0 and 17-10 for its seventh straight playoff win at home.

"It would really be a mistake not to remember the connection and relationship between the team and 'The 12th Man,' the fans," Seahawks coach Pete Carroll said on the field after the game. "It's really unbelievable."

Kaepernick piled up 130 yards rushing, including a 58-yard scramble in the first half that set up Anthony Dixon's 1-yard touchdown for a 10-0 lead.

Sherman celebrated Smith's interception on his back in the end zone.

Replays showed him slapping Crabtree on the butt (he was penalized) and making a choking gesture after the play, but before he screamed into Fox sideline reporter Erin Andrews' microphone after the game that we was "the best corner in the game" and called Crabtree "a sorry receiver."

Kaepernick had 3:37 and three timeouts to work with in the final drive and completed 5-of-6 passes -- including a 17-yard throw to Frank Gore on fourth down -- moving San Francisco from its own 22 to the Seattle 18-yard line before the interception.

Kaepernick passed for 153 yards with a touchdown and two interceptions and had 98 yards rushing in the first half.

The fifth-seeded 49ers, in the NFC title game for the third straight season and looking to go back to the Super Bowl after losing to Baltimore last year, had an eight-game winning streak snapped.
