He says that after such a long lay-off all he can do is take it one session at a time.
Clark has managed just four games since he suffered a Lisfranc injury (a foot problem) against Greater Western Sydney in round 13, 2012.
At the time he went down his fearless approach and accurate goalkicking was a shining light for Demons' fans and winning him respect among football watchers.
He had kicked 29 goals in 11 games, which was enough to win the club's goalkicking award that season.
The loss of his inspiring leadership had an enormous impact on the Demons and his aborted effort to come back last year was a disappointment for all.
"I can't afford to look too far ahead because a lot can change in a week and being out for so long I just need to get to a point where I am able to get through the weeks," Clark said.
He had a solid block of training before Christmas, so he can afford to be managed through January, running alone at training and rebuilding confidence in his body.
Clark said his foot was feeling fine and his simple aim for this season was to play as many games as possible.
He is highly regarded at Melbourne and was on Wednesday named in the leadership group for the third year in succession, a vote of confidence that he will return in good shape.
"The biggest way for me to have an impact is to be out there so that is what my main goal is - to be out there as much as I can and play a role for the team," Clark said.
Ideally he will perform that role inside 50 alongside fellow forwards Jesse Hogan and Chris Dawes. The three forwards have not yet trained together, let alone played together but their relationship is such they should not take long to jel.
On paper the trio looks formidable, but the first question will be whether they can get enough quick supply from their midfield to test opponents.
The second will be whether they can develop running patterns and understanding to create space and support each other when the ball does arrive.
Clark relishes the uncertainty, excited at the prospect of lining up alongside Hogan and Dawes as well as other potential forwards such as Jeremy Howe, Shannon Byrnes and Dean Kent.
"I have no doubt that we can all work together and hopefully cause some headaches up there," Clark said.
Clark has had enough headaches in recent years to last a career, but the experience has made him more empathetic to the trials and tribulations of teammates.
The 284 days that have lapsed since he last played seem an eternity for the 26-year-old athlete and his supporters.
"I'll do everything I'm told, but I'll be doing everything I can to be out there as soon as possible. [I] can't wait to play footy again," Clark said.
Confidence is high that a fruitful season is ahead of him. Impatience won't help him one bit.
When asked if he has a return date in mind he is clear: "I'll play when I'm ready."
