LeCras, who underwent surgery to have a plate inserted into his right arm, will resume either this week or next after making a speedy recovery.
Defender Eric Mackenzie will miss his second straight match due to a hamstring injury.
Daniel Kerr is a chance to play after getting through a WAFL game unscathed, but the Eagles may opt to give him one more hit-out with East Fremantle to ensure his match fitness is up to scratch.
Josh Kennedy, who booted five goals from 11 possessions against Hawthorn, conceded the absence of ruckman Nic Naitanui and Kerr in the midfield had hurt the Eagles’ ability to get the ball forward.
But the 25-year-old is confident the team can turn that trend around, starting with Saturday's clash with struggling Melbourne at the MCG
"We're winning clearances but we're not getting it directly inside 50," Kennedy said.
"We're just not getting enough purchase on our kicks.
"We're going a bit too wide.
"It's something we'll focus on."
Jack Darling, who kicked three goals from eight disposals against the Hawks, echoed those sentiments.
"It's a bit frustrating," he said.
"We just haven't had much clean ball movement inside 50.
"So once we get that happening we can work for each other with our blocking and leading patterns, and have the opportunity."
Melbourne enter the match on the back of horror showings against Port Adelaide and Essendon, with their 148-point loss to the Bombers heaping massive pressure on coach Mark Neeld.
But Kennedy said he hadn't bought into talk that this weekend would deliver a guaranteed win for the Eagles.
"No game's a guarantee, unless they don't rock up. We haven't won a game this year either, so we're both in the same boat," he said.
