Portadown have accepted a position in this summer’s Setanta Sports Cup - but the postponement of the draw has left the future of the competition as uncertain.
Ronnie McFall’s men gained entry into the cross-border tournament via league position and it is understood Crusaders, Glentoran and Glenavon would also represent the Danske Bank Premiership.
Shamrock Rovers, Cork City, Dundalk and St Pat’s were the sides from the Republic of Ireland.
However, demands by other clubs relating to fixture arrangements placed the whole 2015 tournament at risk.
Portadown officials were waiting for confirmation from the Irish Football Association last night (Tuesday) connected to the participation of other clubs.
News from the IFA that the draw - planned for tomorrow (Thursday) in Dublin - has been postponed suggests the 2015 tournament is now under threat.
Quarter-final dates were as follows: Saturday, June 20; Monday, June 22; Tuesday, June 23 and Wednesday, June 25.
The format this year would be a straight knockout draw, with the semi-final scheduled provisionally for the week starting August 10.
Each participating club would receive 4,000 euros - with 30,000 euros for the winners and 15,000 going to the runners-up.
The side having to travel to Cork would pocket an extra 1,000 euros due to additional costs.
Clubs would also keep ticket sales from away ties as an extra incentive to maximise travelling support.
