The GAA has announced that the new disciplinary rules will apply in all championship matches from Sunday. The new rules were approved by Congress last month. The changes include the introduction of the yellow and red card system, a quicker availability of the referee's report and the new method in which all disciplinary hearings, arising out of championship matches, will be handled by the Games Administration Committee at Croke Park.

The GAA state the changes include:

A - A player who has his name taken for a cautionable offence or foul will be shown a yellow card.

B - A player who has already been cautioned, will be shown a second yellow card, followed by a red card and will be sent off the field of play for the the duration of the game only (this would have resulted in a two-week suspension previously).

C - A player who commits an ordering off offence will be shown a red card.

D - All referee's reports arising from senior championship games will be dealt with by the Games Administration Committee, as distinct from the relevant Provincial Council as previously.

E - Referee's reports will be submitted to the GAC within three days of the game or within 24 hours if deemed necessary.

F - Sean McCague, the president elect of the GAA, has been appointed to the National Referee's Appointment Committee. Already on the committee are Frank Murphy of Cork, who is chair of the GAC, and Paddy Collins of Westmeath, who is chair of the National Referee's Committee.
