While Martin escaped suspension for making unreasonable and unnecessary contact to the face of Nick Robertson, he will be walking a tightrope for the rest of the season after being fined for separate incidents by the MRP.
The midfielder will be suspended for one match – and ruled ineligible for the Brownlow Medal – if he commits a third low-level offence this season after also being charged with rough conduct on Brisbane Lion Lewis Taylor on Monday.
Martin was fined $1000 for his bumping Taylor behind play in the opening minute of the game, and $1500 for making "unreasonable and unnecessary contact with an open hand" to Robertson's face.
The MRP graded the second offence as careless conduct with low impact to the head after deciding the open-handed action was not a strike but remained significant enough to draw a charge.
