The Super Bowl is one of the most eagerly anticipated sporting events of the year, as the culmination of the NFL season sees the two best teams from the NFC and AFC do battle to see who will be crowned the victor.
Here we have picked out the five biggest shocks in Super Bowl history.
5. Super Bowl XLIX: New England Patriots 28, Seattle Seahawks 24
The Seattle Seahawks were defending champions and looked to have this Super Bowl all sewn up as they led 24-14. However a late rally from the New England Patriots saw them take a 28-24 lead.
With 26 seconds on the clock Seattle made its way to the one-yard line, with the expectation that they would hand it off to star running back Marshawn Lynch and secure victory.
Seahawks coach Pete Carroll instead called for a passing play, but the Patriots defence stood firm, producing a shock end to this Super Bowl and a win for the Pats.
4. Super Bowl LII: Philadelphia Eagles 41, New England Patriots 33
The Philadelphia Eagles came into Super Bowl LII as underdogs, with many pointing to a mismatch at the quarterback position between all-time great Tom Brady and Nick Foles.
However Foles caught a touchdown pass himself as part of a trick play as the Eagles ran out 41-33 winners thanks to the unusual play call.
3. Super Bowl III: New York Jets 16, Baltimore Colts 7
Joe Namath led the underdog New York Jets to this victory against the well-fancied Baltimore Colts in an early Super Bowl upset.
The Colts had gone 13-1 in the regular season and they were considered far superior to the Jets team, to the extent that they were 18-point underdogs. The Jets victory remains one of the most famous Super Bowl moments.
2. Super Bowl XLII: New York Giants 17, New England Patriots 14
The Helmet Catch Game saw the double-digit favourite New England Patriots outdone by the New York Giants.
This low-scoring affair is mainly known for one play, however, as wide receiver David Tyree made an unlikely catch with the help of his helmet after Eli Manning had thrown to him under pressure.
Plaxico Burress scored the winning touchdown with just 35 seconds remaining and the juggernaut Patriots, who were aiming for an unbeaten season, were stopped.
1. Super Bowl LI: New England Patriots 34, Atlanta Falcons 28
A New England Patriots win in Super Bowl LI looked more than unlikely as they were 28-3 down to the Atlanta Falcons late in the third quarter of this matchup.
However a Tom Brady engineered comeback, coupled with a Falcons collapse, led to the two teams drawing level at 28 apiece to send it to overtime, before the Patriots completed the unlikeliest of comebacks in shocking fashion and secured top spot in this list of the Super Bowl’s biggest ever shocks.
