Keegan Brooksby suffers a blood clot in his arm that will rule him out for the rest of the season.
"Earlier in the week Keegan presented with swelling in his arm," Gold Coast general manager of football Marcus Ashcroft said.
"Medical staff discovered a clot in the large vein in his arm and Keegan was subsequently admitted to hospital for ongoing investigation and management.
"Keegan will be required to remain in hospital for a few days and he will receive medication, which will preclude him from training and playing.
"Unfortunately, it is anticipated that Keegan will not play again this season."
