CELTIC chief executive Peter Lawwell will leave the club at the end of June.
Dominic McKay will switch from his post at Scottish Rugby to take the post as his replacement.
Lawwell has decided to retire after 17 years in the role.
McKay has been with Scottish Rugby for 13 years and was promoted to chief operating officer in 2015.
Lawwell, in a report in BBC Scotland, said: “I believe the cub have identified an excellent successor with the highest integrity.”
The 61-year-old former accountant has been at he helm during a time when the Glasgow club have won 29 trophies, including 13 league titles, four domestic trebles and participation in the last 16 of the Champions League on three occasions.
But the Hoops have endured a testing campaign with failure in Europe in both the Champions League and Europe Cup, a shock Netfred League Cup exit against lowly Ross County and have fallen 23 points behind in the pursuit of a historic tenth successive title.
