North Melbourne defender Griffin Logue has failed in his attempt to fight his careless conduct charge that was initially handed down on Saturday evening.
Logue will now miss North's annual Good Friday SuperClash against Carlton at Marvel Stadium, with the 24-year-old's one-week ban upheld after a two-hour hearing.
Logue will also be joined on the sidelines by former teammate Blake Acres after the first-year Blue proved unsuccessful in lobbying to have his own rough conduct charge thrown out.
Kangaroos' stopper was originally hit with the charge after colliding with Hawthorn's Will Day during the North's lost to Hawthorn in Launceston on Saturday.
Fighting the charge at the Tribunal on Tuesday evening, Logue was represented by Ben Ihle KC, with Ihle contending that his client never intended to bump Day and that Logue was simply trying to win the football.
When presenting evidence, Logue also stated that he never once made the conscious decision to initiate body contact with Day and that if he had careened to a halt to avoid impact, he would have left himself open to injury.
The league, represented by Nick Pane KC, contended that irrespective of intentions, Logue owed Day a duty of care and that the former first-round draftee had made no clear attempts to try and win the ball.
The Tribunal found that Logue had "entered the contest at speed" and despite "initially preparing to bend low to pick up the ball, he changed his intention".
Alastair Clarkson will now be left to ponder how to fill his defensive void, as the Arden Streeters set themselves to do battle with Carlton's dual offensive threats in Charlie Curnow and Harry McKay.
Clarkson was already without the services of McKay's identical twin brother, Ben, with the 25-year-old missing the opening month of the season due to a foot injury.
Clarkson's opposite number, Carlton coach Michael Voss, now has headaches of his own after new Blue Acres also failed shake off a separate rough conduct charge.
Acres was slapped with his charge after making contact with Giants small forward Brent Daniel during Carlton's hard-fought win in the Harbour City.
The winger's team contended that the impact made with the Giant was low to negligible, a point aided by GWS' statement that Daniel was not expected to miss any training during the lead-up to Round 4.
However, the league's legal team, again led by Pane, quickly refuted this claim, stating that given the footage, Acres' initial impact classification of 'Medium' "may be seen to be conservative."
Pane professed that Acres had made a bee-line toward Daniel and that given the Blue's elbow was tucked in, it was fair to assume that Acres had intended to bump, rather than smother the ball.
Intriguingly, Acres' representative, Peter O'Farrell KC, presented that his client's elbow sat close to his body as the 27-year-old had been nursing a pectoral injury at the time.
Acres revealed that he had received a jab for the ailing muscle at half-time and was unable to raise his arm.
However, in spite of O'Farrell presenting his client's GPS data in an effort to prove the midfielder decelerated before colliding with Daniel, Acres will remain out of selection contention for the Good Friday fixture.
The opening bounce of the all-Victorian fixture is scheduled for 4:20 pm (AEST) on Friday afternoon at Marvel Stadium.
