The Pittsburgh Steelers will retire the No. 32 jersey of Franco Harris as part of a weekend-long celebration to honor the 50th anniversary of the Immaculate Reception.

The number is only the third to be retired by the Steelers, joining Ernie Stautner (70) and Joe Greene (75). 

"The Immaculate Reception marked the turning point in franchise history," team president Art Rooney II said. "My grandfather once was quoted saying, 'Before Franco got here, we didn't win much. Since he got here, we don't lose.' I think that sums it up pretty good. Franco's impact on the franchise would be hard to overstate."

Harris' number will be retired at halftime of the Dec. 24 primetime game against the Las Vegas Raiders. The Steelers will also wear a special yellow patch on their jerseys honoring the 50th anniversary of the game.
