The Scottish FA has revealed head of referee operations John Fleming had died after a “prolonged illness”.
The 62-year-old led the nation’s referees for eight years.
Fleming joined the SFA referee development department in 2009. As a category one official he served as a FIFA assistant referee between 1994 and 1997, including at Euro 96.
Rod Petrie, Scottish FA president, said: “John was a private man and many people will be shocked to learn of his passing after an illness borne with fortitude. His commitment was unstinting to the game, his refereeing colleagues and the association.
“He worked tirelessly in support of his match officials, whom he considered an extended family. He undertook his responsibilities as head of referee operations with passion and integrity, qualities that met with respect across the game: in boardrooms, in dressing rooms and, of course, in referees’ rooms.
“John was a dedicated family man and suffered the loss of his wife Ann with the love of his children Dawn and Graham, and of course his grandchildren Anna, Charlie and Rose, on whom he doted. Our thoughts are with his family.
“I know I speak on behalf of the board, John’s friends and colleagues within the Scottish FA, the referee community and clubs across the country in saying that we will miss a trusted colleague, a man of honour and principle, and a dear friend.”
