Celtic wore black armbands during their win over Kilmarnock on Saturday after the death of Billy McNeill, and the Hoops have now suffered further sad news with the passing of Stevie Chalmers.
Chalmers played for Celtic from 1959 until 1971 – scoring an impressive 155 goals in 283 league appearances.
The club statement read: “It is with great sadness that we announce the passing of Stevie Chalmers, our loving father and devoted husband to Sadie.
“The Celtic legend was surrounded by family when he sadly passed away early this morning (Monday, April 29).”
Chalmers spent 12 seasons with the Hoops, winning six league titles, four League Cups and three Scottish Cups.
His most famous outing in a Celtic shirt came in May 1967, as Chalmers scored the winning goal to help his side win the European Cup with a 2-1 victory over Inter Milan.
Celtic hero Chris Sutton was quick to pay tribute to the former Scotland international with a tweet.
He said: “Such a sad week. RIP Stevie Chalmers.”
The club statement mentioned that Chalmers has been battling illness, with the dementia sufferer losing his battle at the age of 83.
It continued: “In recent times Stevie endured the toughest of battles, but just as he approached every game in a green and white jersey, he tackled his long-term illness with much bravery and dignity.
“Stevie, first and foremost, was a family man to his loving wife Sadie; their children, Stephen, Carol, Paul, Ann, Martin, Clare, grandchildren, great grandchildren and wider family members.
“He was also part of a wider family and community. His place in history is assured as one of the famous Lisbon Lions who lifted the European Cup for Celtic in 1967 when Stevie scored the winning goal to defeat Inter Milan 2-1 in Portugal.
“He felt honoured and privileged to have played alongside the Lisbon Lions, and this camaraderie and friendship carried on long after their playing days as the team became lifelong friends.
“Celtic was an integral part of Stevie’s life and he devoted much of his career to the famous Glasgow club. He was adored by Celtic supporters in Scotland and around the world, especially for his passion, loyalty and integrity.
“He felt humbled and honoured when inducted into the Scottish Football Hall of Fame in 2016.
“Stevie was a role model for all, especially to his children growing up. In later years, he doted on his grandchildren and they, too, were a great source of love and laughter for Stevie.
“A true gentleman, who will be sadly missed by so many, but will never be forgotten… The legend lives on.”
