So, to say that it's a big ask for the Matt Williams/Steph Nel coached Irish combination, is putting it mildly. They came together for their first session on Monday and it's a side whose only international is Justin Fitzpatrick on the bench and he was only added to the side when Connacht's Ronan McCormack cried off.
It is an opportunity for players to show their mettle and the spotlight will settle mainly on Bryn Cunningham at full-back, Gavin Duffy in particular, and David Quinlan in the centre, Brian O'Riordan at scrum-half, hooker, Paul Shields, Munster lock Donncha O'Callaghan, flanker Johnny O'Connor and number 8 Des Dillon.
