The Dublin County Board have confirmed that tonight's scheduled senior football championship semi-finals in Parnell Park have been postponed.
St Oliver Plunketts/Eoghan Ruadh have obected to the fielding of Gary Mullin by Na Fianna in last Saturday's quarter-final.
Plunkett's, who lost to Na Fianna in last weekend's quarter-final, claim that Mullins' transfer from Claremorris to the Mobhi Road outfit is void as he was living in Chicago at the time and he played in two championships in the same season.
Kilmacud Crokes are unwilling to play their semi-final against UCD until the date of the other tie between Na Fianna and St. Vincent's becomes known.
Na Fianna are facing the prospect of being ejected from the Dublin senior football championship.
The Dublin GAC will hear the case on Friday, October 13.
