Scottish Football Association compliance officer Vincent Lunny is leaving his post after "the fastest three years of my life".
Lunny joined the Scottish FA from the Crown Office and Procurator Fiscal Service in October 2011 as its first-ever compliance officer.
He will leave the SFA in September to train to become an advocate.
"It has been a real privilege to have worked at the Scottish FA and it has been a tremendous experience," he said.
The SFA will seek to employ a new compliance officer in the near future.
"The last three years have flown by - the fastest three years of my life," said Lunny.
"I've thoroughly enjoyed my time here and in Scottish football but I am also looking forward to progressing my legal career.
"The process of becoming an advocate started back in 2005 for me, and I just completed my entrance exams in February.
"I now have nine months of training ahead of me, commencing in October, and I am looking forward to the challenges that lie ahead."
