The FAI Junior Cup final between Sheriff YC and St Michael's has been postponed after Limerick side Aisling Annacotty lodged a protest on Thursday afternoon.

Dublin club Sheriff were beaten by Regional 1-0 in the quarter-finals but were reinstated into the competition after a successful appeal on the basis that their opponents fielded an ineligible player.

Westport lodged an appeal after their loss to Aisling Annacotty in the quarters - they believed Annacotty had played an ineligible player - but that was unsuccessful.

It meant that Sheriff faced Aisling Annacotty last Sunday in the AUL Complex in north Dublin, a game the Mark Quigley-managed side edged thanks to a penalty from former St Pat's, Dundalk and Drogheda United midfielder Stephen Maher.

That set up a final showdown with Tipperary outfit St Michael's at the Aviva Stadium but a last-ditch protest from Aisling Annacotty has resulted in the showpiece game being called off.

"The final, which was due to take place on Saturday, May 11 between St Michael's AFC and Sheriff YC, has been postponed on the decision of the FAI Junior Council Key Committee," a statement from the FAI read.

"Aisling Annacotty have lodged a formal protest against Sheriff YC, following their semi-final defeat on Sunday, May 5."

The appeal will now be examined in full before a decision is made.
