Richmond star Dustin Martin could be in hot water with the MRO following his side's clash with GWS on Saturday.

The 2017 Brownlow medallist had a day to forget after getting tagged out of the game by GWS’ Matt De Boer, also getting in Martin's head.

A frustrated Martin gave a way a free kick for this incident behind the ball and could miss next week's game if found guilty by the MRO.

The Tigers travel to Adelaide Oval next Saturday to take on Port Adelaide.
