Midfielder Bryce Gibbs has been withdrawn from the side set to take on St Kilda on Saturday afternoon.
Gibbs did not fly with the team on Friday as he was given extra time to overcome a bout of gastro.
Coach Don Pyke told reporters on Friday he was hopeful the 30-year-old would recover, but unfortunately he has not.
The Crows will take on the Saints from 4:35pm AEST at Marvel Stadium.
