Edinburgh boss Alan Solomons has stepped down from the job with immediate effect, with Duncan Hodge appointed in temporary charge.
Hodge has been appointed to take on the job of acting head coach with Stevie Scott and Peter Wilkins remaining in their current roles.
Scottish Rugby Chief Executive, Mark Dodson, said: "Alan came in as head coach at a difficult time in Edinburgh Rugby's history and helped to stabilise and strengthen the club.
"He achieved some notable successes including leading the first Scottish team to a European Final of the Challenge Cup in 2015 and back to back 1872 Scottish Cup victories over Glasgow Warriors.
"Duncan brings his recent coaching experience from the Scotland national team as well as his long playing career with Edinburgh into the role and he will receive our full support to keep moving the club forward.
“I would like to take this opportunity to thank Alan for his significant contribution to the Edinburgh club and I wish him well for the future.”
Solomons said: "I have decided to step down. I understand Scottish Rugby have appointed Duncan Hodge as the new acting head coach and I wish him well.
"I have greatly enjoyed working with the players and coaches and feel I have helped to put the club on a much stronger footing over the past three years and am leaving it in a better place than when I arrived."
