San Juan - A calf injury has forced loosehead prop Wyn Jones out of the Wales team to play Argentina in San Juan on Saturday in the first of a two-Test series.
Rob Evans comes off the bench to replace Jones in the starting line-up for the seventh match between the countries in Argentina with each having won three.
Nicky Smith, part of the run-on team in a 22-20 victory over South Africa in Washington last weekend, takes the place of Evans on the bench.
The two Tests form part of the build-up for Los Pumas and the Dragons for the 2019 Rugby World Cup in Japan.
Kick-off is at 21:40 SA time.
