"In recent times we have made a number of key decisions, relating to both football personnel and other areas of strategic focus, with a view to best preparing the club for a post (COVID-19) pandemic Australian sporting landscape," Fagan said in a statement on Thursday.

"The CEO who leads the club through this process must be in it for the long haul and I am not that person."

Fagan said he believed the chief executive's job should not be "a long-term role for any individual".

Fagan's resignation means the Crows, who finished bottom last season for the first time since the club's 1991 inception, will have two new off-field leaders.

Former SA premier John Olsen was appointed club chairman last October, replacing Rob Chapman who held that post for a dozen years.

Olsen said a replacement for Fagan would be found as soon as possible.

"Given the much talked about changes that have taken place, including the commencement of a rebuild of the playing list and development of a new strategic plan following the global pandemic ... the timing is now right," Olsen said in a statement.

"When Andrew first arrived at the Crows, he spoke openly about his term being in the vicinity of five to seven years.

"We now need a CEO who will steer the club through this next phase and Andrew will continue in his role for some time to come to assist in the transition process."
