Carlton have announced four more list changes for the 2021 season.

Harrison Macreadie, Callum Moore, Fraser Phillips and Cameron Polson have all been informed that they won't be offered new contracts.

Blues Head of Football Brad Lloyd thanked the quartet for their contributions to the club.

“It has been an incredibly difficult period for these out-of-contract players but Harrison, Cameron, Fraser and Callum have been terrific with how they have handled the situation, which is a real credit to them,” Lloyd told carltonfc.com.au.

“Their contributions to the Club, not only as Carlton players but as Carlton people, were certainly valued. All four of them are quality people who really helped to create the sense of unity felt amongst the playing group this year, especially during the months spent together in the hub.

“We thank each of them for their hard work and dedication at Carlton.”

Additionally, the club has committed to re-contract Matthew Kennedy via the upcoming Rookie Draft, while Matthew Owies will be retained as a Category B rookie.

The four players delisted join Hugh Goddard, Darcy Lang, Finbar O'Dwyer, Ben Silvagni and retirees Matthew Kreuzer and Kade Simpson in departing the club.
