THEIR own fresh injury concerns and Adelaide's lack of height in defence could mean that Greater Western Sydney might not automatically revert back to using Rory Lobb in the ruck in Saturday night's clash in Canberra.

The Giants lost four players from last week's win over Carlton, with Toby Greene (hamstring), Brett Deledio (calf), Sam Taylor (hamstring) and Dawson Simpson (ankle) all missing this week.

They've been buoyed by the return of Dylan Shiel, Tim Taranto, Ryan Griffen and Sam Reid for the Crows match, but none of that quartet can fill the void left by Simpson, who has been in solid form over the past seven games.

He's unlikely to play again this season.

Lobb started this year as the club's number one ruckman after the retirement of Shane Mumford, so there's little doubt he can step in. However, the West Australian has been important playing as a permanent tall forward across the second half of the season.

The absence of Adelaide's number one key defender Daniel Talia (shin/calf) adds to the intrigue surrounding the Giants' set-up, with a forward line containing Lobb, Jeremy Cameron and Harry Himmelberg sure to cause the visitors some headaches in the air.

GWS has used Lobb, Himmelberg, and Adam Tomlinson in the ruck at various stages, and Himmelberg said on Friday that his team's versatility means they have plenty of options to use in the ruck against the Crows.

"We'll roll a few through there," he said.

"Rory is a really good option for us forward because he's such a good mark, but he'll definitely play some more minutes in the ruck, which he's done before.

"It's good when big 'Lobby' is down there because he always gets the biggest defender, so I don't have to worry about them.

"But it won't really affect us, I'll play my role. If that’s to play a bit taller and bring the ball to ground, then that's the way it goes."

Cameron made a seamless return from his five-game suspension against the Blues, booting four goals, while Himmelberg and Tomlinson grabbed three apiece.

Himmelberg said getting the star back for four games before the finals can only help the Giants' forward line function more effectively.

"To get the click between players especially in the forward line, you have to have that continuity and play together," he said.

"Hopefully we can build on that starting this week.

"We've had to deal with injuries all year so it's no different this week, it doesn't really faze us."
