Carlton has made four changes to its list ahead of the upcoming trade period, delisting Cameron Giles and Matthew Watson, along with rookies Blaine Johnson and Fraser Russell.

It takes the total number of list changes to at least eight, with Andrew Carrazzo, David Ellard and Chris Judd retiring, and Lachie Henderson requesting a trade.

Carlton’s Head of Football Andrew McKay has thanked the players for their commitment and dedication during their time at Ikon Park.

“Each of these players has made a contribution to our football club and I would like to thank them for their hard work over the journey,” McKay said.

“Matthew Watson departs after 23 AFL games and Blaine Johnson after seven; both provided some exciting moments for us.

“Unfortunately injury restricted Cameron Giles to just seven games in the VFL and much of his time at Ikon Park was spent in rehabilitation. He should be commended for all his hard work and the way he went about his rehab.

“Likewise Fraser Russell, who was a Category B rookie, never made his debut at the senior level, but he worked hard and made a solid contribution to the Northern Blues.

“On behalf of everyone at Carlton I would like to wish these players all the very best for the future.”

The AFL Trade Period begins on Monday 12 October, while the 2015 NAB AFL National Draft will take place in Adelaide on Tuesday 24 November.
