Carlton has made eight changes to its senior and rookie lists ahead of the upcoming trade and draft periods.

Luke Mitchell, Patrick McCarthy, Marcus Davies and Aaron Joseph have been informed that they will not be offered new contracts.

Joseph departs after 73 senior games for Carlton, having made his debut for the Club in Round 1, 2009 against Richmond. 

The 24-year-old went on to be named Carlton's Best First Year Player in 2009. 

Marcus Davies made 17 senior appearances for Carlton after being picked up with selection 43 in the 2009 National Draft, while Luke Mitchell and Patrick McCarthy have each played one AFL game in the navy blue. 

Rookies Rhys O’Keeffe, Frazer Dale and Andrew Collins will also depart, while after 24 games for the Blues Jeremy Laidler has informed the Club he wishes to seek further opportunity elsewhere.  

Carlton General Manager of Football Operations Andrew McKay has thanked the players for their commitment and dedication during their time at Visy Park.

“Each of these eight boys have all made a valuable contribution to the Carlton Football Club and we thank them for that,” McKay said. 

“In Jeremy’s meeting he expressed he would like to look for an opportunity at another Club and we respect and support his decision to do so.

“On behalf of everyone at the Club, I sincerely thank the players for their service and wish them the best for their future football and personal careers.”

The AFL Trade Period begins on Monday 7 October, while the 2013 National Draft will take place on the Gold Coast on Thursday 21 November.
