Deflated Adelaide have lost experienced midfielder Matt Crouch for the rest of the season because of a shoulder injury.
And doubt remains over the fitness of a key duo, captain Jordan Dawson and spearhead Taylor Walker, for Thursday night's game against Richmond.
Crouch received treatment on a shoulder during a loss to Hawthorn on Saturday which extended the Crows' winless record at the MCG to 10 games dating back to July, 2017.
Scans have revealed the 29-year-old will require surgery to fix a damaged AC joint.
"It's really disappointing for Matt who has been playing some great footy this year," Adelaide's high performance manager Darren Burgess said on Monday.
"Unfortunately the severity of the injury requires surgery and he will miss the rest of the season."
Dawson is battling a foot complaint - he passed a matchday fitness test but his output was noticeably reduced when the Crows crashed to a 27-point loss to the Hawks.
"There are a few boys that are a little bit sore and he's another one that ... had a sore foot going into the game," assistant coach Jack Hombsch told reporters of Dawson.
Key forward Walker was substituted at halftime because of his back issue - the 34-year-old missed his club's season opener with a similar complaint.
"We will know a bit more in the coming days, but obviously getting subbed out with the back, he's hopefully recuperating," Hombsch said.
The Crows have slid to 14th on the AFL ladder with only four wins this season, and Hombsch said there was collective disappointment at their lacklustre display against Hawthorn.
The Hawks kicked nine of the initial 11 goals of the game before a belated Adelaide fightback reduced their losing margin.
"Post-game ... it's pretty raw after a game when you're really disappointed as a group," Hombsch said.
"You use today when the air has cleared a little bit and you can sit down and dissect it and try and work out what happened.
"This week we have got a short turnaround ... which coming off a game like the one we had is something we're really looking forward to, because you have got to turn it around real quick."
