Doncaster Rovers chief executive Dave Morris has left the club after more than a decade at the helm.
Morris departed the Keepmoat on Monday after 11 years in charge.
Operations director Gavin Baldwin will oversee the running of the club as interim chief executive until the end of the season.
Morris said: “Doncaster Rovers has been a fantastic place to work and, as a fan myself, it’s been wonderful to see the club move from the Conference to the Championship.
“I’ve overseen many changes in the time I’ve been here, including the move to the new stadium, and I feel now is a good time to move on and seek a fresh challenge.
“The club has a great deal going for it and, with the senior management team I’ve helped to put in place, we have good people who can help take Doncaster Rovers forward.
“Working with Doncaster Rovers has been a real privilege – it’s not always been easy but it has been a fantastic journey.
“The club has a good support network with very proactive and vocal fans, strong community and educational links and passionate people working for it.
“I wish Doncaster Rovers, and those involved, all the best.”
In Morris’ time at the club Rovers has been named business of the year, had accolades for making outstanding contributions to the town, been shortlisted for Football League awards and helped raise more than £50,000 in partnership with the NSPCC.
