Toby Bedford will front the AFL tribunal next Monday as GWS try to overturn his one-game ban for rough conduct.
The Giants small forward is out of their elimination final on Saturday week against St Kilda at the MCG if the challenge fails.
Bedford was charged for his block on Carlton defender Zac Fisher in the third quarter of Sunday's win at Marvel Stadium.
The contact was graded as careless, medium impact and high contact.
GWS unsuccessfully challenged Bedford's one-game game earlier this season for a dangerous tackle.
Bedford has played 16 games in his first season at the Giants after he was traded from Melbourne.
