It comes just three weeks after the Match Review Panel cleared Mitchell of wrongdoing in a similar clash with Adelaide skipper Taylor Walker that left the star Crow with a corked thigh.

However, Lyon said he had no problem with Fyfe's aggressive spoil on Hawk Taylor Duryea that could earn the star Docker a second fine of the season.
