Scott Field will be leaving The FA in February 2016 to join the British Olympic Association as its Director of Communications, it has been announced.
As Head of Media Relations, Field joined The FA in 2009 from Watford Football Club, having previously worked for West Bromwich Albion Football Club.
FA Chief Executive Martin Glenn said: "I am naturally disappointed that Scott is leaving but I am equally delighted for him that he is able to further his career in sport.
"We wish Scott all the best in his new venture and would like to thank him for his commitment and hard work at The FA."
Field added: "I have enjoyed every minute of my time at The FA and have had the privilege to work alongside some fantastic executives, coaches and players.
"I truly believe that working at The FA is the pinnacle of jobs in football and I leave behind an organisation that has a great future ahead under the leadership of Martin and the senior management team.
"Having worked in football for 15 years I am excited by a new challenge within sport, but I will always remain a champion of The FA and all that it stands for.
"I wish Roy and the team all the best for the European Championship Finals in France."
The organisation will be looking to announce interim arrangements as soon as possible.
