GAA director general Páraic Duffy has revealed that there has been no approach to the GAA for the use of Croke Park for a potential 2023 Rugby World Cup bid.

There has been mounting speculation that the IRFU may be preparing a bid to host the World Cup in 12 years.

Any such bid would almost certainly rest on the use of Croke Park, but Duffy claims that he has heard nothing from the IRFU about a bid.

"There has been no approach made to us at all on this subject," Duffy told the Irish Times.

"Obviously Croke Park wouldn't be a problem, as its use has been cleared by Central Council but the use of any other GAA grounds would require a change of rule."

In 2005 the GAA back the decision to open up Croke Park to rugby and soccer during the redevelopment of the old Lansdowne Road stadium. Central Council then subsequently approved the availability of the stadium for further matches should it be required.
