West Coast coach John Worsfold will assess all options before making a decision on the structure of his team's forward line to face Hawthorn.
The Eagles omitted key forward Quinten Lynch from the team which played Collingwood as Josh Kennedy made his return from an ankle injury.
The decision was based on the team's ability to use resting ruckmen Dean Cox and Nic Naitanui as tall forwards and predicted wet weather on Saturday night.
Worsfold said it came down to either Lynch or one of the ruckman to miss out but added West Coast would look to use the four talls again.
"Suffice to say that we wanted to go in with a similar line-up to the previous week in terms of our forward structure, so Kennedy came back in and Lynch missed out," he said.
"Jack (Darling) is a little bit of a different player to Lynch. They're not exactly the same.
"The mix we felt we had with (Darling), (Josh Hill) and our ruckmen up there was the one we wanted to go for."
The form of West Coast's small forwards has come into question, with Ashton Hams dropped from the line-up for the Collingwood clash.
Hill had a quiet night against the Magpies, gathering only five possessions and kicking one goal.
But Worsfold said he had a role to play for the team outside of kicking goals.
"He kicked four a few weeks ago," he said.
"We don't have goals set as targets for him.
"He's got a role to play in terms of helping the other players keep the ball in there, create opportunities for other guys.
"His game against Collingwood was on the quieter side. It wasn't up to the normal level we know he can bring but that's sort of one out of the last three or four weeks that we thought he was below par."
Brad Dick has put pressure on Hill and Hams in the WAFL with nine goals in the past two weeks and Worsfold said he was a "big chance" to come into the team.
Worsfold would not rule out a finals return for Matt Rosa, who fractured his collarbone in a collision with Will Schofield and Chris Dawes.
"(Rosa) is still a chance to get back and play, so he'll just do what he's got to do after his operation," Worsfold said.
"It won't be too long before he's able to get running and then it's a matter of when he's allowed to start tackling and things like that.
"You could bring him straight back in, I've got no doubt about that. He won't have missed enough footy. He'll be running fit and all that sort of thing.
"You don't know how sharp they're going to be with their actual touch and decision-making when they first come in, but that's the decision we'll have to make at the time."Rosa missed the Eagles' 2011 finals campaign with a knee injury.
