Patriots quarterback Tom Brady's post-season successes continued as he led his team to a 35-31 win over the Baltimore Ravens.
The quarterback with the most play-off wins in history threw for 367 yards and accounted for four touchdowns.
The Patriots' running game was non-existent - their 14 yards the fewest by a winning team in post-season history.
But Brady put the Pats' offense on his back, distributing the ball to seven different receivers led by Rob Gronkowski with seven receptions for 108 yards and one touchdown.
Patriots wide receiver Julian Edelman, a college quarterback from Kent State, threw a 51-yard touchdown pass to Danny Amendola on a trick play that quickly erased the Ravens' 14-point lead with four minutes, 20 seconds remaining in the third quarter.
The Patriots will meet either the Indianapolis Colts or Denver Broncos in the AFC Championship game.
Joe Flacco continued his great post-season play, setting a new NFL record for throwing at least two touchdowns in eight straight postseason games.
Flacco passed Terry Bradshaw, Joe Montana and Drew Brees who were tied with seven straight games.
Not to be outdone, Brady's touchdown pass to Brandon LaFell in the fourth quarter marked his 46th career post-season touchdown, which passed Montana's previous mark of 45.
Flacco completed 28 of 45 passes for 292 yards and four touchdowns.
The Seahawks were a little more comfortable in a 31-17 victory against the Carolina Panthers.
Russell Wilson, who is expected to become the NFL"s highest-paid quarterback, had three touchdowns and 268 yards.
With the win the Seahawks will play in their third NFC Championship, their second in as many seasons, when they host either the Dallas Cowboys or Green Bay Packers.
