Ireland A coach Allen Clarke has made five changes to the side to face Argentina A in Saturday's Churchill Cup plate final in Chicago.
Their last game was a 34-12 defeat to England Saxons in the final group game in Toronto last Saturday.
In the backs, Mark McCrea makes a return on the right wing, while Darren Cave and Frank Murphy both come in for their first starts of the tournament.
In the forwards, Denis Fogarty returns in the number two jersey and Connacht flanker Johnny O'Connor is reinstalled at openside flanker, with both players having come off the replacements bench in the Saxons game.
There is one tournament newcomer on the Irish bench with Ulster's Paul Marshall providing back-up at scrum-half. Marshall was not in the original squad and was called up with Tomas O'Leary ruled out of the Argentinian game.
Saturday's game is the third successive Churchill Cup plate final for the Ireland A team. They beat the Saxons 30-27 in the 2006 plate decider in Edmonton and they retained the title twelve months ago at Twickenham thanks to a nail-biting 22-21 win over Scotland A.
Ireland A: Denis Hurley, Mark McCrea, Darren Cave, Keith Earls, Brian Tuohy, Jonathan Sexton, Frank Murphy, Cian Healy, Denis Fogarty, Mike Ross, Donnacha Ryan, Bob Casey (c), Neil Best, Johnny O'Connor, Roger Wilson.
Replacements: Tom Court, Sean Cronin, Trevor Hogan, David Pollock, Paul Marshall, Ian Keatley, Fergus McFadden.
