The new faces . . .
JAMIE HAGAN (26)
(London Irish, tighthead)
Leaving Leinster, this is a big chance to make his mark before moving to London.
ROBBIE HENSHAW (19)
Henshaw has had a standout first season and can become just the fourth teenager to play for Ireland in the professional era if picked to face the States.
Kieran Marmion (21)
Marmion had a great year at Connacht, but faces stiff competition from Isaac Boss and Paul Marshall for the No 9 shirt.
Tommy O'Donnell (26)
O'Donnell has finally established himself as a top Heineken Cup player and has eyes on the No 7 shirt on tour.
Stuart Olding (20)
(UIster, utility back)
Olding's end-of-season form merits his place and Joe Schmidt will be delighted he has shaken off injury to make the trip.
Mike Sherry (24)
Flown out for the 2011 World Cup, Sherry has had to bide his time, but can win his first cap and go on from there.
