Aberdeen striker Darren Mackie will not be offered a new contract at the end of the season.
He is one of six first-team players who have been told he is no longer part of manager Craig Brown's plans.
Defenders Rory McArdle and Youl Mawene, midfielder Yoann Folly and strikers Mohammed Chalali and Danny Uchechi will also be leaving Pittodrie.
Goalkeeper Jamie Langfield and striker Josh Magennis have been offered new deals.
Mackie, 29, has spent his whole career with the Dons, apart from a loan spell with Inverness Caledonian Thistle in 2004, and was given a testimonial against Villarreal in July.
"It is never easy telling a player that his future lies elsewhere and it is one of the worst aspects of being a manager," said Brown.
"I'd like to thank all of the guys who are moving on for their contribution, in particular Darren, who has been a fantastic servant to this club, and wish them all the very best for the future."
Chief executive Duncan Fraser added: "I'd like to echo Craig's comments, in particular regarding Darren, who has been a tremendous ambassador for this club for such a long time, with a first class attitude, both on and off the park."
Icelandic international Kari Arnason rejected a new contract offer at the turn of the year, while defender Mark Reynolds will see his loan from Sheffield Wednesday expire at the end of the campaign.
