There is speculation this morning that just three of the five Garth Brooks concerts will go ahead at Croke Park.
According to the Irish Independent, Dublin City Council bosses are considering granting a license for only three of the five gigs.
It is believed they are looking into whether two of them could be moved to the Aviva or the RDS.
Garth Brooks is due to play five nights at Croke Park from Friday 25 July.
Last week the head of the Labour Relations Commission called for the GAA to re-state its commitment to holding no more than three concerts in a row at the stadium.
