The Crows will consider taking a small and mobile forward line into Saturday night's clash with Essendon at Adelaide Oval.
With Josh Jenkins (rib) and Mitch McGovern (hamstring) both sidelined, captain Taylor Walker is the only key forward left, while Andy Otten can also be thrown into attack.
Medium-sized forward Troy Menzel played well when he came into the side for an injured Walker in the round one win against Greater Western Sydney.
Ruckman Reilly O'Brien could also be handed his third AFL game to play in attack and to back up Sam Jacobs in the ruck.
Crows assistant coach James Podsiadly said they weren't locked into replacing McGovern with another tall forward.
"It's a bit about form as well," Podsiadly said.
"We had a tall out in round one, Tex (Walker) didn't play, and we put a small in.
"I don't think it's too much of an issue for us.
"We play guys who are in form and that can play the role."
The Crows are the highest-scoring team in the competition on their way a 3-0 start to the season.
McGovern met the surgeon on Wednesday afternoon to decide whether he will need to undergo surgery.
He is the sixth Crows player to have a hamstring injury this year after Walker, Brad Crouch, Jake Lever, Kyle Cheney and rookie-listed defender Alex Keath.
"We review our medical staff every week and our medical staff and our fitness team do a wonderful job in trying to work out the exact reason for every injury," Podsiadly said.
"There's no correlation with all the hamstring injuries we've had so far from what my understanding is.
"It's not a concern at this stage."
Crouch had 40 possessions in his first game back in the SANFL last weekend after missing the past three months.
Podsiadly said it was more than likely Crouch would be given at least another week in the club's state league team to build his match fitness.
"His talent at the SANFL level is outstanding and AFL level, too," Podsiadly said.
"I think we've got to build with him, he missed a fair chunk of pre-season, so we're not going to do anything silly with Brad.
"He'll work his way back into the team."
Jenkins is a week-to-week proposition after scans revealed significant damage to the costochondral cartilage as well as deep thoracic bruising.
"He hasn't improved as well as he would've expected," Podsiadly said.
"He was doing a little bit of exercise and was in a little bit of discomfort.
"It's just the cartilage from my understanding of it, so it's just going to take some time to heal, whether it's a couple more days or weeks, we don't really know."
