In what has been called both the greatest and the most controversial game in the history of the National Football League, the Pittsburgh Steelers defeated the visiting Oakland Raiders on a most unusual play on December 23, 1972 in Three Rivers Stadium. A Pittsburgh sports announcer called it “The Immaculate Reception”.

Immediately after the play, one official signaled a touchdown. A long conference among officials followed. After a mysterious telephone call, the decision was made final. Raider Defensive Back George Atkinson once explained that because “…the public was deceived, the officials were deceived, and we (the Raiders) got deceived”, the play is known in Oakland as “The Immaculate Deception”.

Behind 7-6, with 22 seconds remaining in the 15-minute (playing time) fourth quarter, Steelers Quarterback Terry Bradshaw threw the ball on fourth down (last of four plays the offensive team has to move the ball 10 yards) and 10 yards still to make.

Officially, Oakland Defensive Back Jack Tatum got between the ball and Receiver John Fuqua, and it bounced off Tatum’ hands. Under NFL rules, if a pass is touched by or touches an eligible receiver while the ball is in the air and still in bounds, then only that player can legally catch the ball. If, on the other hand, the ball touches or is touched by a defensive player or by a defensive player and eligible receiver simultaneously, any offensive player can make the legal reception.
