North Melbourne midfielder Brent Harvey is appealing his two-match ban for striking West Coast's Adam Selwood.
Harvey was cited for striking the Eagles midfielder in the Roos' 96-point thrashing in Sunday's elimination final, and after failing to have the ban overturned at the tribunal on Tuesday, the AFL confirmed Harvey is taking matters further.
The 346-game veteran has not missed a match since injuring his elbow in 2009, stringing together 77 consecutive matches.
That streak has come to an end after he was also banned for four matches in a separate incident on Sunday - a ban he also challenged, and failed to overturn, at the tribunal.
The appeal will be held on either Tuesday or Wednesday next week, but should he fail to overturn the decision, he will miss the opening six matches of the 2013 season.
In other club news, small forward Matt Campbell was arrested after refusing to leave Crown Casino in the early hours of Wednesday morning.
Campbell - who has played 82 games for the Kangaroos, including 15 this season - was alleged to have caused damage to a Crown staff member's car while being escorted from the premises.
He was question by Victoria Police and released, with the club to determine whether it will take disciplinary action against the 25-year-old.Campbell had arguably his best two games for 2012 in the past fortnight, collecting 20 disposals and kicking three goals in the Kangaroos' win over Greater Western Sydney in Round 23, before also kicking three goals in their loss to the Eagles at Patersons Stadium.
