Ziebell collected Lyons during the second quarter of the Kangaroos' one-point loss to the Crows at Etihad Stadium on Sunday.



The MRP decided the bump was reckless and included contact to the head but was of low impact.



Ziebell's initial sanction was a two-game ban. However, his poor recent record has gone against him in a big way.



Because he has been suspended for seven matches within the past two years, Ziebell copped a 50 per cent loading.



When his 67.5 carryover points were also added, the tally of demerit points reached 405, meaning a four-match suspension.



If Ziebell lodges an early guilty plea, he can have the ban taken back to three games, meaning he would miss North Melbourne's upcoming clashes with St Kilda (Etihad Stadium), Gold Coast (Metricon Stadium) and Fremantle (Patersons Stadium).



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



He copped three matches for flattening St Kilda skipper Nick Riewoldt late in the 2011 season.



He 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.



Brown collected Jamison during the third quarter of the Lions' loss to the Blues at the Gabba on Saturday night.



The MRP assessed the incident as intentional, low impact and high contact.

Richmond's Shane Edwards has been offered a $1950 fine after being booked for pushing Essendon midfielder Dyson Heppell into an umpire during Saturday night's Dreamtime at the 'G game at the MCG.



But Fremantle's Alex Silvagni has emerged unscathed after the match-day report laid against him for rough conduct against Melbourne onballer Nathan Jones was thrown out.



The high contact that Collingwood ruckman Darren Jolly made with Sydney Swans forward Ben McGlynn on Friday night was also looked at, but the MRP decided the force used was below that deemed to be reportable.

NORTH Melbourne's horror run has continued, with midfielder Jack Ziebell facing a three-match suspension after being cited by the Match Review Panel for a high bump on Adelaide's Jarryd Lyons.The Brisbane Lions have also suffered a blow, with Jonathan Brown set to miss Friday night's big clash with Collingwood after being offered a one-game ban for striking Carlton defender Michael Jamison.
