WEST Coast forward Mark LeCras will miss this week's top-of-the-table clash with Fremantle after accepting a one-match suspension from the Match Review Panel.

Essendon midfielder Adam Cooney also looks set for a stint on the sidelines after being sent to the AFL Tribunal for his bump on Greater Western Sydney's Stephen Coniglio.

LeCras will be absent for perhaps the biggest Derby in West Australian history after he was booked for his high bump on Hawthorn's James Frawley.

The MRP graded the contact as medium impact to Frawley's head, which drew a two-game sanction. Because of LeCras's good record was able to reduce the penalty to one game with an early plea, which the Eagles announced on Tuesday morning.

His absence will hurt the Eagles, who already look set to lose defender Jeremy McGovern to a hamstring injury.

Cooney will front the Tribunal on Tuesday after the MRP chose to pass on the case, likely due to its grading system delivering an insufficient penalty.

If the MRP graded it intentional, high impact and high contact it would have been sent directly to the Tribunal.

But if the MRP assessed the incident as careless conduct, high impact and high contact Cooney's penalty would have drawn a three-game sanction, which could have dropped to two with an early plea.

Sydney Swans defender Ted Richards was charged with rough conduct for his front-on contact against Geelong forward Tom Hawkins. 

He accepted a $1000 sanction with an early plea after the MRP saw the incident as careless conduct with low impact to the head, and he is free to face Collingwood on Friday night.

Adelaide midfielder Matt Crouch was cleared of his high contact on Richmond captain Trent Cotchin, with the panel agreeing the force was below that required to constitute a report.
