I missed the injury as I was down stairs and came back up to see him being put on to the stretcher, If it's true that the Preston player made a back for him and this injury turns out to be as serious as some are saying, then it absolutely has to be addressed by the league, the act of making a back has only one intent which is to ensure your opponent falls to the ground in a heap, it's been done for years by players at all clubs and will no doubt happen up and down the league's today, it has to become a no go, a straight red until it's removed from the game by the clubs themselves.
