GEELONG coach Chris Scott has blasted the AFL's Match Review Panel, labelling its decisions confusing and inconsistent.

Scott took aim at the controversial match review system at a press conference on Tuesday when discussing the three-match ban handed to North Melbourne midfielder Jack Ziebell.

"I haven't really wasted too much time thinking about it (the Ziebell ban), and I think that's the approach that most people should take to the match review panel," Scott said.

"If you try to work it out you'll just tear your hair out and end up very confused and frustrated.

"They are so inconsistent that any sort of predictions, when it comes to the match review panel, are a waste of time."

Ziebell received a three-week suspension for a high bump on Adelaide's Jarryd Lyons.

North Melbourne decided against contesting the ban on Tuesday, meaning Ziebell will miss games against Gold Coast, Fremantle and GWS.

It is the third time he has been suspended for a high bump.

He was rubbed out for three matches for flattening St Kilda skipper Nick Riewoldt late in the 2011 season, and was then was cited for a high bump on Carlton's Aaron Joseph last July.

North Melbourne took that case to the Tribunal, but the Roos lost and Ziebell was forced to miss four matches.

During his time off he headed to Utah and did some altitude training with the US ski team.
