An early plea would have reduced the penalty to a three-match sanction, but Ziebell will now attend the tribunal on Tuesday night.

Meanwhile North Melbourne will accept the penalties handed down to both Sam Wright and Nathan Grima.

The Match Review Panel's findings were as follows:

Jack Ziebell, North Melbourne, has been charged with a Level Three engaging in rough conduct offence against Aaron Joseph, Carlton, during the second quarter of the Round 16 match between North Melbourne and Carlton, played at Etihad Stadium on Friday July 13, 2012.

In summary, due to an existing poor record, his three-match sanction must remain at three matches, even with an early plea.

Based on the video evidence available and a medical report from the Carlton Football Club, the incident was assessed as negligent conduct (one point), high impact (three points) and high contact (two points). This is a total of six activation points, resulting in a classification of a Level Three offence, drawing 325 demerit points and a three-match sanction. He has an existing bad record of three matches suspended within the last three years, increasing the penalty by 30 per cent to 422.50 points and a four-match sanction. He also has 45 demerit points carried over from within the last 12 months, increasing the penalty to 467.50 points and a four-match sanction. An early plea reduces the penalty by 25 per cent to 350.63 points and a three-match sanction.
