Adelaide's triple club champion Rory Laird has been sidelined by a shoulder injury as the Crows prepare to throw an AFL lifeline to Matt Crouch.
Laird has been ruled out of Sunday's MCG fixture against Melbourne after suffering a hit to the shoulder in last week's loss to GWS.
"He's just a little bit banged up," Adelaide coach Matthew Nicks said on Thursday.
"His shoulder is a bit too sore so we won't take a risk.
"There is swelling there at the moment ... we were hopeful he might get a game up this week but in the end it has been too much of a push
"It's disappointing that Lairdy won't be there but we've got guys that deserve an opportunity."
Crouch, who has played just one AFL game this year - against Geelong on May 8 - was at the top of that list.
Nicks said the 2017 club champion deserved reward for consistent performances in the state league and loomed as a like-for-like replacement for Laird.
"Both inside (midfielders), both very good first-hands players," he said.
"Matty has shown all season at SANFL level that he's ready if and when he's called on and it's probably one of those weeks this week.
"This year he has been outstanding. He has led the way at SANFL level."
First-year backman Max Michalanney is set to be rested after playing every game so far in his debut AFL season.
"He's a very honest young kid. He wants to play footy," Nicks said.
"But he also understands that it's a long season."
Nicks said other younger Crows such as Luke Pedlar were also feeling the pinch.
"We've got a few guys that are, as most teams are, grinding at the moment that we'll have a look at," he said.
"We'll try and bring in a little bit of freshness, a little bit more energy, maybe a bit of a spark."
Second-year forward Josh Rachele will serve the first game of his two-match suspension for striking as the Crows seek to rebound after slipping outside the top eight to 12th with two consecutive losses.
