After a busy trade period, which landed Tom Lynch, Lewis Johnston, Joshua Jenkins and Luke Brown and Ivan Maric, Phil Davis, Jack Gunston and Tony Armstrong all leave four more Crows have been told they are no longer required.
That means ten changes to the primary list since the end of the 2011 season, with two retirements - and the Crows still has four spots to fill at the national and pre-season drafts.
“It’s always a tough time of the year and the Club appreciates what these young men have contributed to the Club. All four have outstanding character and we wish them all their best for their football careers," Crows football operations general manager Phil Harper said.
"But we need to keep introducing new talent to the squad and - after a successful trade period - we now have the opportunity to use the drafts to complete our 2012 list.”
Sellar was drafted in 2006 and played 21 AFL games.
Young was drafted in 2007 and played two AFL games last year while Cook, who was also drafted in 2007, played 14 games.
Craig did not play an AFL game in two seasons with the Crows.
Adelaide holds selections 27, 41, 46 and 64 in the 2012 national draft, to be held in Sydney on November 24.
