Dougal Howard must pass a fitness test this week to put himself in the frame for a senior return against the Cats.
The influential defender has not played since leaving the game early against Carlton in Round 16 with a knee complaint.
Max Heath will also seek to prove his fitness this week, as he emerges from concussion protocols.
Dan McKenzie remains at least a week away from a return following a calf strain, while a timeline is yet to be placed on Jack Billings as he continues to recover from a back injury.
|Daniel McKenzie||Calf||1 week|
