Fremantle have dumped Matt de Boer, Tendai Mzungu and Clancee Pearce - all 100-game AFL players - as they continue overhauling their list.
The Dockers also told Jack Hannath his contract will not be renewed.
De Boer (138 games) and Mzungu (102) were members of the team that lost the 2013 grand final to Hawthorn, while Pearce also played 100 matches.
But between them, they only managed a total of 13 AFL matches this season.
Hannath played two senior games for a total of 20 and Grey made three senior appearances.
De Boer and Pearce joined the Dockers through the 2008 rookie draft and Mzungu came to the club two years later as a mature-age recruit.
"The fact that Matt, Tendai and Clancee were able to achieve such important career milestones is testament to their resilience, work ethic and commitment to the club," said Dockers football operations manager Chris Bond.
"Matt and Tendai will also always have the honour of being part of the club's first grand final team in 2013."
Retired captain Matthew Pavlich heads the list of 10 Fremantle players who so far have left the club, not had their contracts renewed or been de-listed.
Fremantle had a disastrous season, finishing 16th after starting the year as top-four hopefuls.
