That's a stupid idea to be honest. If a player deliberately injures another player they get sent anyway under the current system, if they accidently hurts a player they get sent too?
In fact, let's just make it touch football, or have bits of rag tucked into their shorts.
Players get injured in contact sports, fucking deal with it and don't tone down a game that's already been toned down far too much.
Did big league print that as a satirical letter of the week?
I reckon we should make it like the AFL, where players can bash the fuck out of opposition players and all that happens is there's a free kick.
Except they can't bash them in above the shoulders, below the waist, in the back, in the air...
..and if you punch someone, it's a ridiculous monetary amount.
