The GAA looks set to introduce a black card offence should a new proposal be passed at March's Annual Congress in Derry.
Any black card shown to a player will result in a mandatory substitution, and if a team receives three black cards during a match, any subsequent cards will result in a player leaving the pitch with no replacement allowed.
Offences likely to incur a black card from the referee include deliberatively pulling down an opponent or tripping an opponent with a hand, arm or foot.
A deliberate body collision with an opponent after he has played the ball away or for the purpose of taking him out of the movement of play will also result in a black card, as will abusive or provocative language or gestures to players, as well as remonstrating in an aggressive manner with a match official.
“After a team has been give three black cards, any further black cards will mean the player going off with no substitution" - GAA
A GAA statement explained the new proposed system: “The present yellow card system will remain in place with players being sent off without replacement on receiving a second yellow card as now pertains.
“After a team has been give three black cards, any further black cards will mean the player going off with no substitution.
“For inter-county competitions a cumulative total of three black cards or three double yellow cards for an individual in any one grade in the same year will lead to a one match suspension, except where this would apply to an All-Ireland final, in which case the one match suspension is carried forward to the next match.
“The number of substitutions permitted should be increased from the present five to six, to coincide with the introduction of the proposed change.
“The above changes, if approved by GAA Congress, to be implemented from January 1, 2014.”
