The West Coast Eagles and Liam Duggan have withdrawn their tribunal appeal after the defender was admitted to hospital for observation on Monday afternoon.
Duggan, who was handed a one-match ban for a dangerous tackle on Collingwood's Taylor Adams, was set to challenge his suspension on Tuesday night.
The Eagles confirmed the news on Tuesday afternoon.
"The club has withdrawn its challenge to the one-match rough conduct sanction against Liam Duggan," West Coast said in a statement.
"Duggan became ill on Monday evening and has subsequently been admitted to hospital for observation."
