Ireland's Keith Earls and Martin Moore to miss tour of Argentina
Keith Earls and Martin Moore have been ruled out of Ireland's tour of Argentina this month.
Munster back Earls has a viral infection, while a broken toe has forced out Leinster prop Moore.
Ireland coach Joe Schmidt has called up Connacht's Rodney Ah You and Noel Reid of Leinster to the panel.
Meanwhile, Ireland forwards coach John Plumtree will leave the post after the Argentina tour for family reasons.
The New Zealander joined the Ireland national coaching team in September last year.
"I have really enjoyed working with Joe, Les and the players over the last few months," said Plumtree.
"But at the end of the day family must come first and we must do what we think is best for the Plumtree family."
Connacht back Robbie Henshaw and Ulster fly-half Paddy Jackson have also pulled out of the touring squad because of injuries.
The first Test in Resistencia, in the north-east of Argentina, will be played next Saturday.
The second Test will take place a week later in Tucuman, north-western Argentina, both with a 19:40 BST kick-off time.
