A replay of the radio broadcast will be available on the team website.

“In my wildest dreams, I never expected it and, and it never crossed my mind,” Harris said of having his number retired. “It just wasn’t something that was top of mind. The Steelers don’t retire numbers. So you don’t have any thoughts about it. And so when Art mentioned it to me, I was blown away. I mean, that was a wow moment and unbelievable.”

In addition to the fact that Harris snagged the Immaculate Reception, he likewise was a part of four Super Bowls and was the Super Bowl IX MVP. He additionally procured the NFL Offensive Rookie of the Year in 1972 and was named NFL Man of the Year in 1976. He was inducted into the Pro Football Hall of Fame in 1990.
