Scott Lawson and Alasdair Strokosch are once again named amongst the replacements as was the case last week whilst Alasdair Dickinson has recovered from an abdominal upset to take Geoff Cross's place on the bench.
Scotland make just one change to the starting line up following last weekend's 24-16 victory in Tucaman, winger Simon Danielli wins his 26th cap and replaces Nick de Luca, who drops to the bench.
The personnel change means a positional switch for Max Evans, who moves from the wing to outside centre.
Hugo Southwell; Sean Lamont, Max Evans, Graeme Morrison, Simon Danielli; Dan Parks, Rory Lawson; Allan Jacobsen, Ross Ford, Moray Low; Jim Hamilton, Alastair Kellock (capt); Kelly Brown, Johnnnie Beattie, John Barclay
Scott Lawson, Alasdair Dickinson, Scott MacLeod, Alasdair Strokosch, Mike Blair, Phil Godman, Nick De Luca.
