The Super Bowl was played at MetLife Stadium in East Rutherford, New Jersey on Sunday, February 2, 2014. It was the first Super Bowl hosted by New Jersey and the first to be held outdoors in a cold weather environment. The Seahawks scored 12 seconds into the game and held the lead the rest of the way.

Broncos quarterback Peyton Manning was named the regular season's Most Valuable Player (MVP) by the voters of the Associated Press (AP) for a record fifth time after compiling passing stats which included regular season records for passing yards and passing touchdowns. Manning also was named the Offensive Player of the Year for the second time in his career. Carolina Panthers linebacker Luke Kuechly earned Defensive Player of the Year honors.
