North Melbourne has some decisions to make as it looks to replace at least three injured players after a bruising clash with the Hawks last weekend.

A second concussion this season has sidelined Callum Coleman-Jones for the near future, with the ruck-forward now in enhanced protocols.

Given Charlie Comben remains out of action due to an ankle injury, veteran Todd Goldstein shapes as the likeliest inclusion to accompany Tristan Xerri for Sunday's meeting with St Kilda at Marvel Stadium.

Goldstein was a class above in the VFL at Arden Street Oval last weekend, finishing the five-point loss to Box Hill with 28 disposals, 11 marks, 25 hitouts and five clearances to earn nine coaches' votes.

Roving at his feet in the reserves was Hugh Greenwood, who responded to his omission from the AFL side with 24 touches, 13 tackles, seven clearances and a well-taken goal, while young gun Will Phillips also shone with 24 disposals and six clearances.

Either player could be a suitable replacement for the hamstrung George Wardlaw, who has joined Coleman-Jones and Cam Zurhaar (ankle) on the injury list.

Charlie Lazzaro is another onballer who finds himself in the frame following a strong VFL outing.

The 22-year-old gathered 28 disposals and four inside 50s and often looked dangerous on the attack, streaming through the centre with ball in hand.

After shaking off Achilles tightness through the week, defender Aaron Hall performed strongly in the reserves, tallying 11 marks, 10 rebounds and a game-high 43 touches to put his name back into the selection equation.

Down the other end, Kayne Turner pressed his claim for a first senior match since Round 7 by booting two goals and collecting 17 disposals.

Flynn Perez is a chance to return to the line-up but will need to prove his fitness after missing Round 18 due to a knee issue.
