Ahead of the second and final Test of the summer tour, the Ireland coaching team has made eight personnel changes and one positional switch to the side that beat the Pumas 29-17 in Resistancia last Saturday.
Ulster’s Andrew Trimble will retain his position on the wing alongside Simon Zebo and Rob Kearney at fullback. Fergus McFadden lines out at 13 with Darren Cave switching to inside centre. Eoin Reddan comes in at scrum-half to make his tour debut.
Rory Best is named in the front row with Dave Kilcoyne and Mike Ross, while Devin Toner is reunited with captain Paul O'Connell in the second row. Jamie Heaslip and Rhys Ruddock are introduced to the back-row with Chris Henry continuing at openside.
Ulster’s Rob Herring will make his first senior appearance for Ireland off the bench on Saturday, as will Munster's James Cronin and Leinster's Noel Reid. Iain Henderson is also named on the bench.
The second Test will take place at the Estadio Jose Fierro in Tucuman and will be televised live on SKY Sports.
