The Seattle Seahawks are going to the Super Bowl for the second time in two years after clinching a dramatic 28-22 win over the Green Bay Packers in overtime at CenturyLink Field.

Jermaine Kearse strolled in the all-important NFC Championship winning touchdown four minutes into overtime after an inch-perfect 35-yard throw from quarterback Russell Wilson.

Kearse was receiving close attention from Packers cornerback Tramon Williams  as he burst straight down the middle, but such was the quality of Wilson's pass Williams could not get near it, leaving the Seahawks man to just step into the end zone and finish the game.

His efforts mean Seattle will now travel to the University of Phoenix Stadium on 1 February looking to become the first team to successfully defend a Super Bowl title since the New England Patriots won in 2004 and then again 12 months later.

It was a remarkable turnaround considering the hosts were staring down the barrel at 19-7 down deep into the fourth quarter.

The Packers will be left kicking themselves after Wilson, who threw for 209 yards on the day, ran in a one-yard touchdown and Marshawn Lynch took it home from 25 yards to make it 20-19 with minutes to spare.

A successful two-point conversion attempt left the Packers needing a field goal to save their season and Mason Crosby delivered the goods from 48 yards to take it into overtime, but the Seahawks would not be denied for long.
