GWS have made a late change to their squad for Saturday's clash with the Cats at Spotless Stadium.
Defender Zac Williams will miss the game with a hamstring injury, and the Giants will welcome another debutant into the side.
Jeremy Finlayson, who was drafted to the Giants with the 85th pick in the 2014 National Draft, will make his first appearance for the club after developing in the NEAFL since his arrival.
Williams joins Tim Taranto, Harry Himmelberg and Daniel Lloyd on the sidelines this week, with Josh Kelly, Davon Smith and Rory Lobb joining Finlayson as the inclusions.
For the Cats, Lachie Henderson, Zac Smith, Aaron Black and Zach Guthrie have been included, while Scott Selwood, Tom Stewart, George Horlin-Smith and Darcy Lang are all out.
