The AFL Tribunal suspended them both. That was overturned by the Appeals Board.
Both were bad results that favoured big Victorian sides, no arguments there, but I don't think those results should just be accepted as setting a precedent when they were both wrong.
Port can appeal, but I'm not sure under what grounds they would be able to get Houston off. It seems pretty clear-cut.
Can there be an argument the AFL endorses the bump as it is not illegal, the AFL accept the bump is fine in the game as long as the outcome is not concussion.
How on earth can players play under such ambiguity? knowing I am allowed to bump but I will get in trouble if I bump.
The AFL need to take some responsibility.
