Greater Western Sydney's injury curse has continued, with two more players going down, meaning the Giants have only 26 fit players to choose from for this week's clash with West Coast at Domain Stadium.

Veteran Steve Johnson will miss the trip to Perth due to a knee injury flaring up. Rory Lobb, meanwhile, will miss the match due to a groin injury.

“Steve has been pulling up quite sore in recent weeks and his knee just hasn’t recovered well enough this week so he won’t be available to play," GWS head of athletic performance David  Joyce said.

“Rory has received two heavy knocks to his pelvis in the last fortnight.

“He’s been sore as a result and hasn’t quite got to the level that we need early this week, and we’ve made the early decision to focus on his recovery in order to get him right as soon as possible.

“We’re confident that with the right treatment both players won’t be far away from returning to the field.”

The Eagles host the Giants at Domain Stadium at 4.40pm AEST.
