Gordon Smith has left his post as chief executive of the Scottish Football Association for personal reasons.
The former Rangers striker took up the post in 2007, having formerly worked for BBC Scotland as a sports pundit.
In a statement, the SFA said: "Gordon Smith has resigned from his post as chief executive. A further statement will be issued tomorrow."
Smith played for Kilmarnock, Rangers and Brighton, while he had a spell as assistant manager with St Mirren.
But Smith was better known as a regular voice on BBC Scotland's football programmes Sportsound and Sportscene.
He also owned a players' agency but gave up both interests when he took up the role at Hampden after agreeing to succeed David Taylor.
When he took up the role in June 2007, Smith said he was prepared for the flak that would undoubtedly come his way.
