North Melbourne will be forced into at least two changes when it takes on the in-form Cats in Hobart this Saturday.
Robbie Tarrant's availability will depend on him making it through main training, with the veteran defender a potential welcome inclusion against Geelong's potent forward line.
Jack Mahony had been in impressive form as a pressure forward prior to his injury against Essendon, but should be available for selection.
With Cam Zurhaar under an injury cloud, Eddie Ford looks a chance to make the starting 22 for the first time. The young forward has been an impressive performer at VFL level so far in 2021.
Aiden Bonar has stepped up his recovery in recent weeks, and should be in the frame for selection against the Cats. He had arguably his best game in the royal blue and white the last time the two sides met, putting in an impressive performance on Patrick Dangerfield.
Lachie Young and Kyron Hayden have both featured at AFL level in 2021, and provide depth in the backline.
Patrick Walker has been named as an emergency in recent weeks, and the classy defender/winger could be in the mix for a debut.
Tom Campbell continues to dominate in VFL games and scratch matches, and looks ready to go should David Noble and the match committee call on him.
Jared Polec made his return to the team as the medical sub, and may be considered for a return to the 22.
Charlie Comben has been earmarked for a late season debut, but Round 20 is likely to be too early for the 200-centimetre prospect.
