Greater Western Sydney forward Jon Patton has been withdrawn from the side's clash with Melbourne on Saturday afternoon.
Patton was initially named in the side when teams were announced on Thursday evening, however, he was under an injury cloud and has now been withdrawn due to a hamstring strain.
Harrison Himmelberg, who recently signed a two-year contract extension, has come into the side, while Daniel Lloyd has been added to the emergencies.

The injury means the Giants will be light on for key forwards, with fellow forward Jeremy Cameron also out with a hamstring injury for the crucial clash, meaning Rory Lobb will play a lone hand up forward.
