North Melbourne will be forced into making at least one change for its clash with Fremantle on Saturday night at Optus Stadium.

Charlie Comben is set to miss the next 2-3 weeks due to a shoulder injury, opening up a position in Alastair Clarkson's backline.

Aidan Corr has featured nine times in the senior side this season but is unavailable due to a calf issue which will put him out of action for 3-4 weeks.

Kallan Dawson shapes as a potential replacement for Comben, after gathering 12 disposals, five marks and three intercepts in the 13.7 (85) to 6.8 (44) VFL win over Werribee on Saturday.

In his return from concussion, youngster Matt Whitlock could be around the mark for a recall after 12 touches, five rebound 50s and four marks against the Tigers. Wil Dawson is another option, despite being trusted as a key forward for most of the reserves' campaign so far.

Eddie Ford is a smaller alternative but has been a prolific interceptor since being thrown behind the ball in the VFL. He grabbed 14 intercepts against Collingwood in Round 9, and 10 against Richmond in Round 8.

Will Phillips will again raise his hand for selection following a dominant performance in the midfield at Avalon Airport Oval.

The onballer picked up 22 touches and was a brick wall in defence, laying 21 tackles for the day.

Bailey Scott's name will also be on the radar after tallying a team-high 26 disposals against Werribee, as will Geordie Payne's, after the second-year Roo laid 13 tackles and grabbed 12 possessions.

Tall forwards Callum Coleman-Jones and Finnbar Maley both put in strong shifts and are chances of being flown over to WA to face the Dockers.

Maley was at his aerial best, coming away with three contested grabs to stake his claim for an immediate recall, while Coleman-Jones chipped away in his second game back, finishing with 17 hitouts, 14 disposals, seven clearances and five score involvements.

Mid-season draftee Zac Banch starred against his former club, kicking three goals from 13 disposals against Werribee.

In his first game wearing the blue and white stripes, the small forward was terrific and relentless with his pressure, VFL coach Tom Lynch said post-game.
