Gale became ill several years ago...

He deteriorated so much that he struggled to even move or speak in his final years.

Although amazingly, he did manage to show up to the Bears100 celebration last year...

And the reaction from fans clearly moved him.

His 7-year career went fast but made a lasting impression...

Gale scored 56 career touchdowns, as well as rushed for 4,956 yards.

And we all know about his friendship with Brian Piccolo...

Which made us love him even more, and was depicted in the award-winning movie, "Brian's Song."

Gale and Brian became close friends as well as teammates.

Sayers stayed by Piccolo's side after being diagnosed with cancer and remained close till his death in 1970.
