GREATER Western Sydney has been hit with a blow ahead of its clash against Geelong, with star forward Toby Greene ruled out with an ankle concern.

Daniel Lloyd was named as his replacement.

Greene, 23, was injured at a training session the day before the game.

The Cats have to deal with their own worries with skipper Joel Selwood not having recovered from a concussion he suffered in the two-point win against Fremantle last Sunday.

It looms as a match with top-four ramifications. Going into the game, GWS was second and Geelong was third.
