HAWTHORN’S Ben McGlynn has failed to get his rough conduct charge downgraded from reckless to negligent, a result that will see him miss the next four matches.

McGlynn was charged with engaging in rough conduct against Port Adelaide's Kane Cornes during the first quarter of their match at Aurora Stadium on the weekend.

The incident was assessed as reckless conduct (two points), medium impact (two 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 93.75 points carried over from within the last 12 months, increasing the penalty to 418.75 points and a four-match sanction.

The failure to change the penalty means the 22-year-old will miss his team's clash with the as-yet undefeated Bulldogs.
