Hawthorn's Sam Mitchell and St Kilda's Dean Polo have accepted $900 fines for making making negligent contact with an umpire.

These were the only two charges laid by the match review panel following the opening round of the finals series.

A match-day report against Hawthorn's Jordan Lewis was thrown out, allowing the midfielder to be free to play in Friday night's knockout semi-final against Sydney at the MCG.

Lewis had been booked for engaging in rough conduct against Geelong's Joel Selwood during the second quarter of last Friday's qualifying final at the MCG.
