Seven members of Aberdeen's first-team squad have been told their contracts will not be renewed at the end of the month while two others are free to move on.
Manager Derek McInnes, who took over from Craig Brown earlier this year, has also told four of his U20 party they will be leaving the struggling SPL club.
Former Scotland internationals Gavin Rae and Gary Naysmith are among those not to be offered new deals along with Rory Fallon, Mitch Megginson, Rob Milsom, Isaac Osbourne and Dan Twardzik.
Midfielders Stephen Hughes and Jordon Brown have been told to look for new clubs while young quartet Scott MacAulay, Zach Szemis, Stuart Close and Jamie Hamilton are also on the way out of Pittodrie.
Speaking on the club's official website, McInnes said: "It's one of the least enjoyable aspects of the job to tell players they won't be staying and I would like to thank them all for their contribution to this club.
"Each of them are excellent professionals and we wish them all the very best in their future careers."
