Cork and Waterford face win-or-bust Munster hurling clash

Weekend's GAA preview: Ulster football rivalries back in the spotlight as Cork and Waterford face win-or-bust Munster hurling clash. The much-maligned round-robin series got a shot in the arm last weekend with Dublin's victory over Galway and Cavan derailing Mayo. On Saturday, Derry get the chance to further complicate matters when they face Armagh while Donegal host Tyrone in two of the biggest football fixtures of the weekend. On Sunday, we'll find out who will play Kilkenny in the Leinster hurling final in what is effectively a semi-final meeting between Galway and Dublin. Meanwhile, in Munster Cork will have to lift themselves off the canvas after last week's drubbing by Limerick as they face Waterford in Páirc Uí Caoimh. This will be a knock-out clash, with the losers set to crash out of the hurling championship.
