Untried Fremantle ruckman Lloyd Meek will make his AFL debut in Saturday's season-opening clash against Melbourne.

The Dockers on Wednesday confirmed that the 22-year old big man would play his first game at senior level in the Round 1 MCG clash.ย

Meek was drafted to Fremantle with Pick 69 in the 2017 AFL draft and finally gets his opportunity while impressing over the pre-season amid the club's ruck injury crisis.

Rory Lobb is set for a lengthy stint on the sidelines after straining his ACL, while Sean Darcy is racing the clock to be fit for Round 1 with his own knee issue.

Furthermore, draftee Josh Treacy was handed a two-match ban for striking during a WAFL practice match over the weekend.

Dockers coach Justin Longmuir praised Meek's perseverance at a team meeting on Wednesday where he revealed he would make his debut.

"The reason why this excites me is because I don't think there is anyone at the club that has worked as hard on their game as Meeky has this year," Longmuir said, according to fremantlefc.com.au.

"The thing I love about you mate, is you've stepped up to every challenge that we've thrown at you.

"You've stepped up this preseason and you deserve this opportunity.

"You'll be coming up against one of the best, but you are ready, so go out there, play your game and enjoy it."

Meek is coming off a strong performance against Nic Naitanui in Fremantle's AAMI Community Series clash against West Coast - where he tallied 12 disposals and 18 hitouts.

The Dockers could yet take two rucks into their matchup against Max Gawn and the Demons, with Darcy officially listed as a test on the injury report.

The Demons and Dockers meet on Saturday at the MCG at 1.45pm AEDT.
