Hibernian have confirmed managing director Fife Hyland will leave the club at the end of the season.
Hyland - who joined the board in 2008 - informed chairman Rod Petrie last year of his intention to quit.
Scott Lindsay will return to the post of chief executive - which he previously held from 2008-2010 - and will take over responsibility for the commercial and communications operations from Hyland in the next few weeks.
Hibs have also announced the appointment of Brian Houston as a non-executive director.
Chairman Rod Petrie said: "I should like to thank Fife for the experience, flair and acumen he has brought to the club's commercial and communications operations.
"We understand his decision and wish him every success in the future. I am grateful too, that Scott Lindsay has agreed to return to his role as chief executive of the club."
Hyland said: "I have enjoyed the privilege of serving on the board over the past four seasons, and will deeply miss not being part of the club day-to-day and working with such dedicated people.
"Being commercial director, then managing director of Hibernian, was a true honour and the time is now right for me to move on to other projects.
"I'd like to thank both Rod and Scott in particular for their support and counsel, and the board and supporters of Hibernian for the opportunity to represent the club.
"I'll be fully committed to helping the team succeed to the end of the season."
