Live on BBC Radio 5live and the BBC Sport website
Scotland will take on Argentina in Sunday's World Cup quarter-final in Paris with the same starting line-up and replacements that beat Italy 18-16.
"We are getting to the stage where we have a group of guys who have played five games together in seven weeks," said head coach Frank Hadden.
"It made sense to go with a side that is prepared for this."
Argentina goalkicker and leading points scorer Felipe Contepomi has recovered from a flu bug and will play.
Contepomi has played at fly-half for the Pumas during the tournament but lines up in the centres alongside brother Manuel against Scotland.
It means that coach Marcelo Loffreda has kept faith with the starting XV that defeated Ireland 30-15.
But there is one change on the bench, with London Irish number eight Juan Martin Leguizamon returning from injury to nudge Martin Durand out of the replacements.
Scott Murray fails to make Hadden's 22 while Rob Dewey again beats Andrew Henderson to the inside-centre berth.
Nathan Hines and James Hamilton are the starting locks, with Scott MacLeod on the bench.
Scotland have not beaten Argentina since 1990 but Hadden hopes continuity of selection will work in his favour at the Stade de France.
"We have made progress and we are expecting an even bigger performance this weekend," said Hadden.
"There are plenty of tools in the tool box. Now it is just a case of using the right tool in the right place and at the right time in this important match."
The Scots will hope to continue their remarkable kicking record - they are the only side who have not missed one in this World Cup.
