The 0 for 4 Curse is the name of a superstition or scapegoat used to explain the Super Bowl drought that both the National Football League's Minnesota Vikings and Buffalo Bills have had to endure since losing their fourth Super Bowl game in team history.
The Vikings lost Super Bowls IV, VII, IX, and XI. The Bills were defeated in Super Bowls XXV, XXVI, XXVII, and XXVIII.
The Denver Broncos were said to have broken the curse when they won Super Bowl XXXII. They previously lost Super Bowls XII, XXI, XXII, and XXIV.
