Harris played for the Steelers from 1972 to 1983, making nine Pro Bowl teams and helping guide Pittsburgh to four Super Bowls titles.
The then-rookie back propelled the Steelers to the first of those four Super Bowls against the Raiders on Dec. 23, 1972, when a desperation heave from Terry Bradshaw caromed off the helmet of safety Jack Tatum and into Harris' hands, allowing him to scamper into the end zone for a game-winning touchdown.
The play is, by all accounts, one of the most iconic moments in professional sports history. It made Harris an instant Pittsburgh legend, and he went on to rush for 11,950 yards and 91 touchdowns over his career with the Steelers. He remains the franchise's all-time leader in rushing yards and touchdowns.
While some fans will be shocked to learn Harris' number wasn't already retired by the Steelers, it was largely a formality. The team has several numbers that are unofficially retired—meaning the team doesn't use them but has not formally taken them off the table forever—and Harris' No. 32 was among those.
Ernie Stautner's No. 70 and Joe Greene's No. 75 were the only officially retired numbers before Tuesday's announcement.
