On December 23, 1972, in a controversial play that is known as the “Immaculate Reception,” rookie running back Franco Harris of the Pittsburgh Steelers grabs a deflected pass from quarterback Terry Bradshaw to score a touchdown, winning the game for the Steelers 13-7 over the Oakland Raiders.

The historic play took place during the semifinal playoff game of the American Football Conference (AFC), in Pittsburgh. Ken Stabler of the Raiders scored a touchdown with 73 seconds left in the game, putting Oakland up 7-6. Things looked dark for the Steelers, a struggling franchise that had finished 31 of the previous 39 seasons with a losing record. Bradshaw’s pass, launched from the Steelers’ 40-yard-line, was intended for halfback Frenchy Fuqua. When the Raiders safety Jack Tatum collided with Fuqua at Oakland’s 35-yard-line, the ball bounced backwards in a huge arc for a total of seven yards, where Harris scooped it up before it hit the ground and ran 42 yards into the end zone.

Though one official, Adrian Burk, immediately ruled the play a touchdown, there were no other signals. Tatum swore he didn’t touch the ball and that it had bounced off Fuqua and ricocheted towards Harris; this would have made Harris’ play illegal, according to a rule at the time stating no two receivers can touch the ball consecutively on the same play. From a dugout on the sidelines, referee Fred Swearingen got on the phone with Art McNally, the NFL’s supervisor of officials. McNally had access to the instant replay on television from his seat in the press box, and confirmed Swearingen’s ruling that Tatum had touched the football, making Harris’ play a touchdown. In his post-game comments, Raiders coach John Madden indicated that he believed Tatum had made contact with the ball.

It's too bad the tv coverage isn't as extensive and sophisticated as today. It would be nice to know if Tatum really did touch the ball.
