The Pittsburgh Steelers will retire Franco Harris' number 32 in celebration of the 50th anniversary of the immaculate reception, the team announced Tuesday.

It will happen during a halftime ceremony Dec. 24.

The number 32 has not been issued by the Steelers since Harris' last season in Pittsburgh in 1982.

This will be the third jersey number retired by the team.

The immaculate reception is one of the most famous plays in football history. Harris caught the ball just before it could hit the ground and ran it in for a game-winning touchdown during the team's game Dec. 23, 1972, against the Oakland Raiders in Pittsburgh.
