Neither Queen's University nor Sligo IT will take any further part in the Sigerson Cup after being found guilty of fielding ineligible players.
A decision to expel both teams from the competition was taken by the GAA's Higher Education Hearings Committee.
Queen's officials had alleged that Sligo IT fielded an ineligible player, Stephen Doak, in their recent 1-9 to 0-8 defeat after extra-time at the Dub.
Queen's were punished for playing three Stranmillis College students.
The decision means that Queen's have failed in their bid to be reinstated into the competition, although both clubs have three days from the issuing of the ruling to lodge an appeal should they wish.
Doak, who lined out for Sligo in the game, is currently a full-time Sabbitical Officer with Sligo IT Students' Union.
This breach of rule was successfully argued by Queens officials, who included full-time GAA officer Aidan O'Rourke.
However, Queens were also punished for fielding Stranmillis College trio Ciaran O'Hanlon, Tony Donnelly and Greg McCabe in the match.
While all three hold Queen's student cards, and Stranmillis students have been allowed to play for the university in the past, a new GAA club has been set up in the last year at the teacher training college to cater for its players, and will play in the Corn Comhairle Ardoideachais Championship next week.
Weekend hosts UCC now advance to the semi-finals, where they will meet University of Limerick or IT Carlow.
