Davie Wilson's family have revealed the Rangers legend is suffering from dementia.
The Light Blues great has attended Ibrox for many years, even working for the club's corporate hospitality on occasion.
But he has now 'retired' from watching his team in person as he battles the disease.
A statement read: "The Wilson Family would like to announce that due to ongoing Alzheimer’s and dementia issues, Rangers legend, Davie Wilson, has now retired from attending Ibrox on match days to watch his beloved Rangers.
"He was thrilled to see the Gers win their 55th league title and wishes his team all the very best in the forthcoming season."
Wilson remains a Scottish footballing icon with 22 caps for his country and 10 goals, including a home win over England in 1962.
In his 11-year Ibrox spell, the winger lifted 11 major honours from 1956 to 1967.
He also played a huge role in the club's runs to the 1960 European Cup semi-finals and the 1961 Cup Winners' Cup final.
