Stewart Regan has resigned from his position as Scottish FA chief executive.
Regan's resignation comes after eight years in his post, during which he has overseen changes including streamlining the Scottish FA committee system and introducing a more transparent and independent disciplinary process.
It follows the SFA's frustration in replacing former national team manager Gordon Strachan after Scotland's failure to qualify for the 2018 World Cup.
Michael O'Neill turned down the job to remain with Northern Ireland last month, with Scott Gemmill now tipped to fill the role.
Regan says he faced "challenging headwinds" in his role but recognises the "need for change" as he steps down.
He said in an official SFA statement: "I have devoted my time in Scotland to modernising, protecting, developing and promoting the game, whilst facing into some extremely challenging headwinds during my time in the job. While it has been tough, I am proud to leave having overseen a period of significant change and substantial growth following the McLeish Report in 2010.
"We are now at another staging point and I recognise that it is now time for further change. I have decided to step aside to allow new leadership to take the organisation forward.
"I would like to thank the staff for their energy, hard work and support during my tenure. Their love of the game mirrors Scotland's passion for football and I am proud to have served the Association."
The SFA board are scheduled to meet on Thursday to discuss possible candidates for the Scotland managerial vacancy.
