Looks like 4 games in common sense is kicking in at the diciplinary. Not sure that there were huge differences in the Ackers/ O Connor tackles to the ones that players picked up bans for clubs in rounds 1 and 2.
I would hope this would now extend to trying to keep 13 players on the pitch. There was nothing wrong with the on report system. Similar to football the video ref could be used for when the ref is unsighted and there has potentially been a clear red card foul other than that get on with it and deal with it on Monday.
