Former Celtic player and coach Sean Fallon has died at the age of 90.
Fallon made more than 250 appearances for Celtic during the 1950s and was assistant manager to Jock Stein throughout the most successful spell in the club's history. He also earned eight caps for Ireland.
"Celtic legend Sean Fallon has died peacefully at the age of 90. Our thoughts and prayers are with his family," the club statement said.
The Irishman unfurled the Scottish Premier League flag before the champions began the defence of their title at Celtic Park in August last year.
Celtic said Fallon died yesterday morning surrounded by his family.
Chief executive Peter Lawwell said: "Sean Fallon was a Celtic legend who devoted much of his life to the club he loved. He was a supporter, first and foremost, and he was proud to have worn the green and white hoops that he loved.
"He did so with fearless distinction over eight years in the 1950s, and Sean was at the heart of all of our triumphs, including that famous 7-1 League Cup victory in 1957.
"Ten years later, he was part of our greatest ever success, winning the European Cup in Lisbon. Working alongside Jock Stein, Sean helped to deliver that trophy, along with nine consecutive league titles and numerous other trophies.
"He was an integral part of the club's success, and also played a vital role in identifying talented young players who would go on to become great Celts.
"He was a gentleman with a great sense of humour, and always a welcome guest here at Celtic Park. Sean will be sadly missed, but he will never be forgotten."
