GWS will challenge Shane Mumford's striking charge in a bid to have the ruckman available for round three of the AFL season.
The 32-year-old will front the tribunal on Wednesday night in a bid to overturn his one-match ban for striking Sydney's George Hewett in last Friday's practice match at Blacktown.
Match review officer Michael Christian assessed the incident as intentional conduct with low impact to the head.
Mumford is already suspended for the first two rounds of the season after footage dating back to 2015 emerged of him snorting a white powder.
GWS will forfeit a $10,000 fee if the challenge is unsuccessful but Mumford's suspension will not increase from one match.
