Wales international and former Dons loanee Simon Church has retired at 29 over a long-term hip problem.
Church had not played since signing a short-term deal with Plymouth Argyle in January.
He said: “I never thought this day would come but with the medical advice I have received I am now officially hanging up my boots.
“I have been fortunate enough to have lived my dream for 11 years professionally. I have experienced moments you can only dream of when you’re a child.
“Playing for Wales was an absolute honour. The achievements we had as a team are something I’m immensely proud of being a part of.
“The group of boys were the best on and off the pitch I have ever been with.
“I want to thank all the clubs I’ve been at as well as the fans, players, staff and a handful of managers.”
Church made 13 league appearances for the Dons, scoring 6 goals, while on loan from MK Dons.
He scored against Celtic on his debut at Pittodrie as Aberdeen beat the Hoops 2-1.
