Crows ruckman Shaun McKernan will miss Adelaide's round seven clash against Geelong after accepting a one week ban for striking.

Match Review Panel findings:

Shaun McKernan, Adelaide Crows, has been charged with a Level Two striking offence against Alex Johnson, Sydney Swans, during the first quarter of the Round Six match between the Adelaide Crows and the Sydney Swans, played at the SCG on Saturday May 5, 2012.

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

Based on the video evidence available and a medical report from the Sydney Swans Football Club, the incident was assessed as intentional conduct (three points), low impact (one point) and body contact (one point). This is a total of five activation points, resulting in a classification of a Level Two offence, drawing 125 demerit points and a one-match sanction. He has 60 demerit points carried over from within the last 12 months, increasing the penalty to 185 points and a one-match sanction. An early plea reduces the penalty by 25 per cent to 138.75 points and a one-match sanction.
