HAWTHORN’S Sam Mitchell has been unsuccessful in overturning his $3200 fine for making contact with an umpire.

Mitchell made contact with field umpire Stefan Grun during the second quarter of Saturday's clash with Essendon at the MCG.

In other AFL Tribunal cases, Fremantle defender Dean Solomon unsuccessfully challenged his misconduct charge and will be forced to sit out the club's clash with Hawthorn this weekend.

And, St Kilda’s Steven Baker has been suspended for two matches after being found guilty of rough conduct and striking.

Baker received a one-match ban for each of the two charges, but the punishment could have been worse.

Baker was spared a third week on the sidelines after AFL Tribunal chairman David Jones ruled the points he gained from his suspension for rough conduct would not be carried over to striking case, where he was also found guilty.

Baker - who now carries 155 points towards his future record - will miss the Saints' clashes with Sydney this weekend and Hawthorn next week.
