Controversy has arisen surrounding the new black card rule with a Cork college considering an appeal against a result following an alleged mistake by referee Kevin Walsh.
Colaiste Chriost Ri, who lost the Corn Ui Mhuiri quarter-final to Pobalscoil Chorca Dhuibhne of Dingle in extra time, are considering an appeal after the Kerry side’s captain, Barra O Suilleabhain, was apparently issued with both a yellow and a black card during the match in Killarney.
Under new rules, O Suilleabhain should have been red-carded, but Pobalscoil Chorca Dhuibhne were allowed to replace the midfielder with substitute Gareth O Brosnachain.
Munster colleges serving officer John Brennan told the Irish Examiner: "The referee's report is expected tonight and if Colaiste Chriost Ri decide to put in an objection, there will be a hearing of the Munster Post Primary CCC committee.
"They have three days to lodge an objection and we will hold off on fixing a date for the semi-final until the three days have passed."
Chriost Ri manager Aidan Moynihan added: "If that man had not been replaced, the outcome after normal time could have been very different.
"I went on to the field to try and address the issue. I was dismissed quite abruptly by the referee. I was asked to leave the field and if I didn't, I would be put off.
“The linesman on our side was Eddie Walsh, who is from Kerry and part of Eamonn Fitzmaurice's Kerry backroom team. The other linesman was also from Kerry, Pat Sheehy.
"It was a bit of an ambush position to be putting us in having those officials. The new rules are laid out as plain as day on the GAA website."
