Sydney have informed Dean Towers, Jordan Foote, Angus Styles and Jake Brown that they will join Alex Johnson in not being offered a contract for the 2019 season.
Towers was the most experienced of the delisted quartet, playing 57 games across six seasons.
Foote played six games in four seasons, while both Styles and Brown failed to make their senior debuts.
“Dean, Jordan, Angus and Jake have all contributed to our club in their own ways. They worked tirelessly on their craft and depart knowing that they gave it their all,” Sydney Swans’ Head of Football Tom Harley told the club’s website.
“We wish them all the best in their future endeavours.”
