They became even closer after Piccolo pulled himself out of a game early in the 1969 season because of breathing difficulties and was diagnosed with cancer. That phase of their friendship was recounted first by Sayers in his autobiography, “I Am Third,” and then in the 1971 movie “Brian’s Song.”

With actor Billy Dee Williams playing Sayers and James Caan in Piccolo’s role, the made-for-TV movie was later released in theaters.

Sayers stayed by Piccolo’s side as the illness took its toll, donating blood and providing support. Just days before Piccolo’s death age 26, Sayers received the George S. Halas Award for courage and said: “You flatter me by giving me this award, but I can tell you here and now that I accept it for Brian Piccolo. … I love Brian Piccolo and I’d like all of you to love him, too. Tonight, when you hit your knees, please ask God to love him.”

After his playing days, Sayers served as athletic director at Southern Illinois University-Carbondale and founded several technology and consulting businesses.

Sayers made the 130-mile trip from his home in Indiana to attend the opening ceremony of the Bears’ 100th-season celebration in June 2019, receiving a rousing ovation.

“It’s amazing someone that was so beautiful and gifted and talented as a player and later in life to have that happen to you is really, I know, tough on everybody,” Hall of Fame linebacker Mike Singletary said that weekend.
