CARLTON has made a further four list changes, with Liam Sumner and Andrew Gallucci delisted, while Daniel Gorringe and Matthew Korcheck have retired.

It comes in the wake of Kristian Jaksch not being offered a contract for 2018, as first revealed by AFL.com.au.

Sumner, who was drafted with pick No.10 by GWS in the 2011 NAB AFL Draft, played four games this season and has been invited to train with the Blues at the start of pre-season, and remains a chance to again be listed by the club.

Sumner was acquired in a trade with Greater Western Sydney in 2015, while former Sun Gorringe was picked up as a delisted free agent around the same time. Gorringe was drafted with pick No.10 in the 2010 NAB AFL Draft.

American big man Korcheck was rookie drafted at the end of 2015.

Football manager Andrew McKay told carltonfc.com.au Gorringe had struggled with injuries in his time at the club.

"I would like to thank Kristian, Liam and Andrew for their contribution over their time with us. All three players have shown growth and development during their time at the club," McKay said.

"Matthew will return home to the United States, and we acknowledge his commitment to the club over the last two years. We commend his dedication in moving from the other side of the world to try his hand at AFL football.

"Unfortunately, Daniel had a frustrating run with injuries over the past couple of seasons and we totally understand his decision to step away from football at the highest level.

"We wish all five players the very best for their future endeavours."
