The New England Patriots are going back to American football's Super Bowl after seeing off a tough challenge from the Jacksonville Jaguars.
Star quarterback Tom Brady was once again the hero, overcoming a hand injury to throw two touchdown passes in the final quarter for a 24-20 victory.
The underdog Jaguars marched to a 14-3 lead late in the second quarter before Brady and the Patriots launched their comeback.
Running back James White crossed with three-minutes on the clock in the first half to close the gap heading into the break.
Jacksonville stretched the lead to 20-10 with less than 10 minutes on the clock - more than enough time for the 40-year-old Patriots quarterback to pull his side in front.
Two touchdown passes to receiver Danny Amendola, the last with less than three-minutes remaining, got the five-time Superbowl champions the result a thunderous New England crowd was praying for.
They 'Pats' will play the Philadelphia Eagles on January 5 (NZT) after the latter ran rampant over a hapless Minnesota Vikings 38-7.
Inspired by a ferocious defensive display, the Eagles offence had a point to prove, putting the NFL's best defence to shame in front of a raucous Philadelphia crowd.
Would-be experts had written the Eagle off pre-playoffs after star quarterback Carson Wentz suffered a knee injury in December.
Backup Nick Foles, mocked by many, produced a career defining performance throwing for three touchdown passes without turning the ball over.
Receiver Alshin Jeffery caught two touchdowns against a defence that had only leaked more than 17-points once in the regular season.
The Eagles defence squeezed a limp Viking offence into committing three turnovers - two of which produced touchdown plays for the hosts.
The Super Bowl 52 matchup will be a rematch of 2005 when Tom Brady led the Patriots to a 24-21 win over the Eagles.
