Cork Constitution will start favourites even though they could only manage a draw against the Dooradoyle outfit at this venue in February. Regular wing Derek Dillon retains his place in a backline that sees brothers Cian and Conor Mahony in the centre with Brian O'Meara and Ronan O'Gara at half back. In the pack Frank Sheahan is in the middle of the front row.

Shannon will wait until later today before they name their side for the game against Clontarf at Thomond Park. They will give Mossie Lawlor, Derek Hegarty, Andrew Thompson and Alan Quinlan a late fitness test but it is expected that if fit, Quinlan will take his place on the bench alongside Mick Galwey and Peter Stringer.

Clontarf name an unchanged side from the one that defeated Dungannon last time out.
