The Seahawks pulled off a miraculous rally to beat Green Bay in the NFC Championship game and were in position for another improbable victory when Jermaine Kearse made a juggling, 33-yard catch while on his back.
With the ball on New England's one-yard line, Seattle appeared to be headed towards a second straight Super Bowl title.
But Butler spoiled the Seahawks' bid, stepping in front of Ricardo Lockette for the game-winning interception.
