Semple Stadium will host next Sunday's Leinster hurling final replay.
However, a Michael Bublé concert at the Dublin venue on Saturday means Headquarters is unavailable, so a Leinster hurling decider will take place outside Croke Park for the first time since the 1960s.
It will be the first time in the history of the Association that a Leinster hurling final will be played outside the province.
The game will throw in at 3pm and live on RTÉ One.
In the week following Kildare's 'Newbridge or Nowhere' campaign, the decision is likely to raise eyebrows in Waterford, as the county's hurlers were refused permission to play their Munster round robin matches in Nowlan Park as the Kilkenny venue is outside the province.
There is a precedence for a final being played outside a province, with the 2004, 2005 and 2006 Ulster football finals all played at Croke Park.
