The Immaculate Reception is the nickname given to one of the most famous plays in the history of American football. It occurred in the AFC divisional playoff game of the National Football League (NFL), between the Pittsburgh Steelers and the Oakland Raiders at Three Rivers Stadium in Pittsburgh, Pennsylvania, on December 23, 1972. With the Steelers trailing in the last 30 seconds of the game, Pittsburgh quarterback Terry Bradshaw threw a pass to John Fuqua, who was immediately hit and lost possession of the ball. As the ball fell towards the ground, Steelers fullback Franco Harris scooped it up and ran for a game-winning touchdown. The play has been a source of unresolved controversy and speculation ever since, as many have contested that the ball touched either Fuqua or the ground before Harris caught it, either of which would have resulted in an incomplete pass by the rules at the time. Kevin Cook's The Last Headbangers cites the play as the beginning of a bitter rivalry between Pittsburgh and Oakland that fueled a historically brutal Raiders team during the NFL's most controversially physical era.
As a result, the week after this playoff victory, the Steelers lost the AFC championship game to the Miami Dolphins 21–17, who won Super Bowl VII in their landmark undefeated season.
