North Melbourne senior coach Alastair Clarkson says he and his coaching staff will need to transform the look of the backline should Griffin Logue's challenge at the Tribunal fail.

If Logue remains suspended, he, in addition to fellow key defender Ben McKay who is still recovering from bone stress, will miss the Good Friday SuperClash at Marvel Stadium.

The Kangaroos do have some options to available to bring in for Round 4 though, with Kallan Dawson and Aiden Bonar shaping as potential inclusions for Friday evening's game against Carlton and its threatening forward line.

"Bonar is one who played early in the season for us was, was going OK in that spot, so depending on what happens with Griffin at the Tribunal, we'll bring in one or two players that need to try and cover those big fellas for the Blues," Clarkson told reporters on Tuesday morning.

"You know, they're a formidable forward line and very potent in their front end, and (Harry McKay and Charlie Curnow) are Coleman medallists.

"We'll have our challenge set out in that part of the game, but there's other strengths to the Carlton side too that we need to concern ourselves with, particularly the supply that those two guys can get.

"But we might have to innovate a little bit if a couple of our talls aren't playing."

Logue was offered a one-match ban on Sunday after bumping Hawthorn midfielder Will Day in North Melbourne's Round 3 clash in Launceston.

The Roos announced on Monday that they would be challenging the Match Review Officer's decision which Clarkson's believes is the correct action to take.

"It's a really delicate one because the reason we're challenging it is because this (the bump) is in play and you've got a split seconds to make these decisions," Clarkson stated.

"We don't necessarily classify this as a bump as much as it is just two bodies that are coming together.

"I'm not sure if you saw the Gold Coast incident between (Nick) Holman and (Sam) De Koning, you know, there needs to be an element where you protect yourself so you don't clash heads.

"In our view, it happens so, so quickly and that's the reason why we want to get it tested at the Tribunal tonight. Just to get an assessment on what is allowed in the game and what's not.

"The powers that be will make that make that decision, but if these are off-the-ball incidents or it's a player that's definitely contesting the ball and another one's just trying to bump him out of the contest, then it's a different kettle of fish.

"In this instance, we think this is in play and in a split-second the decision's had to be made and that decision in our view was around (Logue) trying to protect himself more so than trying to take a player out."
