VAR manager Jon Moss is set to leave his Scottish FA post after just one month to join another national association.
The Scottish FA confirmed Moss will leave his Hampden role just 51 days after being appointed.
Moss has been offered a "top referee job with an association in a different continent".
Head of refereeing at the Scottish FA Willie Collum said: “I am obviously disappointed to be losing Jon so quickly but this is a once-in-a-lifetime opportunity for him and his family and I wish him the very best on his new adventure.
“It is a measure of the esteem in which he is held in refereeing globally that he has been offered a top job in a different continent.
“The work he has undertaken with us as VAR Manager has already strengthened our operation and we will begin the process of recruiting a replacement immediately.”
Commenting on his departure, Moss said: “I have loved my short time at the Scottish FA and already I believe clubs, players, managers and supporters see a significant improvement under Willie’s leadership.
"Even though my time in Scotland has been short and sweet, I have loved working with the Scottish FA and the VAR team at Clydesdale House.
“I leave with only fond memories and a wish that I could have stayed for longer but this is an opportunity of a lifetime and I look forward to the new challenge, better equipped for it by my experience in Scotland.”
