Gaelic Players Association chief Dessie Farrell has poured cold water on the idea of introducing a penalty points scheme to catch consistent foulers.
GAA President Sean Kelly suggested the idea after a weekend in which a number of players saw red for two yellow cards but players who pick up yellow each week get away.
However, Farrell said: "The problem is that there is a lot of inconsistency in refereeing. What is a yellow card one day is not the next day. It would be difficult to implement the system."
