Former Rangers defender Sandy Jardine has died at the age of 65, the club have confirmed.
The European Cup Winners' Cup-winning full-back was among the Ibrox side's most decorated servants.
Jardine — a 38-time capped Scotland international — was diagnosed with cancer 18 months ago. Rangers boss Ally McCoist said: "There have been many great names associated with Rangers Football Club in our 142-year history and Sandy is a Rangers legend in every sense of the word.
"We are all devastated with the news he has passed away. We have lost a great man today.
"I had the privilege of watching Sandy playing for Rangers when I was a young boy, I had enjoyed the pleasure of working with him closely since I returned to the club in 2007 and he was a truly remarkable human being.
"His achievements both on and off the pitch are second to none and I was honoured to regard him as a friend. He gave everything for this great club and worked tirelessly in a number of roles because he wanted to ensure the traditions, history and standards at Rangers were maintained.
"He was respected not only by Rangers fans but also the wider football community and he is a huge loss to the game. We will never see his like again in the modern era.
"He recently told me he was proud to be a Ranger and wanted to be remembered forever as a Ranger. Well Sandy, you will go down in history as one of the greatest of all time and we will miss you terribly.
"It is a very sad day for everyone associated with Rangers and our thoughts are with his wife Shona, his children Steven and Nicola, his grandchildren and the rest of his family and friends."
As well as representing the Ibrox outfit almost 800 times, the Edinburgh-born defender was also appointed co-manager of Hearts alongside former Light Blues team-mate Alex MacDonald in 1986.
The duo came within three goals of leading the Jambos to the Scottish title, only to lose out in dramatic fashion to Celtic after a infamous last-day defeat to Dundee.
During his Ibrox stint, he won three league championships, five Scottish Cups and five League Cups.
