Clark retired in April, citing the need to focus on his mental health after he had been diagnosed with clinical depression.
After crossing to Melbourne from the Brisbane Lions at the end of 2011, Clark played just 15 games for the Demons because of a recurring foot injury.
However, Clark was outstanding in his first season at Melbourne, kicking 29 goals in 11 games in a struggling 2012 Demons team.
Clark's contested marking and accuracy in front of goal that year were outstanding.
Drafted by the Lions with pick No. 9 in the 2005 national draft, Clark played 82 games in six seasons at the Gabba. He finished third in the Lions' 2009 best and fairest, having played most of that year in the ruck.
The West Australian had appeared set to cross to Fremantle after seeking a trade from the Lions, but the Dees trumped the Dockers at the 11th hour by offering pick No. 12 in that year's draft.
It is understood Clark is keen to ensure Melbourne is adequately compensated if he finds a new home in next month's trade period.
