While some observers and experts may have anticipated sweeping changes to the side that went down to Collingwood in round two, that isn’t the case with an unchanged line-up named.
The announcement means Daniel Pratt, Cam Pedersen and Ben Warren may have to fight it out in the VFL for another week.
The Roos travel to Perth on Saturday afternoon after a light training session at Aegis Park.
It’s the second time this year already the side has had to play at Patersons Stadium after taking on the West Coast Eagles there in round one.
