There's a GAA double bill this Sunday afternoon. First we're heading north to see Derry and Down clash in the Ulster Senior Football Championship quarter final at Celtic Park from 2pm. After that we're heading south to Semple Stadium, where Clare and Waterford go head to head in the Munster Senior Hurling Championship at 4pm. Commentary comes courtesy of Darragh Maloney, Martin Carney, Ger Canning and Michael Duignan, while Colm O'Rourke, Cyril Farrell, Liam Sheedy and Pat Spillane are on hand to analyse all the action.
