Carlton have confirmed that four players will not have their contracts renewed for the 2019 season.
They include ex-Roo Aaron Mullett, former Port player Cameron O'Shea and rookie-listed pair Matthew Shaw and Jesse Glass-McCasker.
The Blues head of football Brad Lloyd thanked the players for their services.
“It’s always a hard time of the year across the industry making list changes and saying goodbye to players,” Lloyd told the club website.
“We wish Aaron, Cam, Matt and Jesse all the best for their future endeavours. They have all contributed strongly to our football program over recent years and should be proud of their achievements during their time at Carlton.”
