No cause of death has been given. However I read that he was diagnosed with dimentia in 2017. It may not have had anything to do with his death. But it's interesting to know.

Relatives of Sayers had previously revealed that he was diagnosed with dementia. In March 2017, his wife, Ardythe, said she blamed his football career.

'Like the doctor at the Mayo Clinic said, "Yes, a part of this has to be on football,"' Ardythe Sayers told The Associated Press from their home Indiana home in 2017. 'It wasn't so much getting hit in the head. It's just the shaking of the brain when they took him down with the force they play the game in.'
