GWS has made a late change ahead of their clash with the Western Bulldogs.
Defender Adam Tomlinson has been withdrawn from their side.
Ruckman Dawson Simpson has come in to replace him.
No reason has been given for Tomlinson's omission, suggesting it may be tactical.
It means the Giants will be reinforced in the ruck, with number one ruckman Shane Mumford out with suspension this week.
The Dogs have gone in unchanged.
