Ulster hooker Rory Best will captain Ireland's 28-man squad for next month's tour to the United States and Canada.
Best, who missed out on selection to the British and Irish Lions squad, leads a squad which includes six uncapped players in Connacht scrum-half Kieran Marmion, Ulster and Ireland U20 centre Stuart Olding, Connacht full-back Robbie Henshaw, Leinster tighthead prop Jamie Hagan and Munster's openside flanker Tommy O'Donnell and hooker Mike Sherry.
Announcing the squads, acting head coach Les Kiss said he expects difficult Tests against two of the game's emerging nations.
"For the North America tour we have selected a squad who I believe have the right mix of youth and experience and I'm really looking forward to working with them over the next few weeks," he said.
"USA and Canada have improved enormously since the 2011 Rugby World Cup and we know we will be in for two tough Test matches."
Ireland face the United States in Houston on June 8 and Canada in Toronto on June 15.
