Cardiff - Cardiff Blues centre Cory Allen is in line to make his Test debut this weekend after being named on Thursday in the starting side to play Argentina.
At the other end of the spectrum, prop Gethin Jenkins will become only the fourth player to win 100 Wales caps after Stephen Jones, Gareth Thomas and Martyn Williams when he takes the field at Cardiff's Millennium Stadium on Saturday.
Wales coach Warren Gatland made four changes to the side beaten 24-15 by South Africa in Cardiff last weekend.
Allen replaced the injured Jonathan Davies in midfield while fly-half Dan Biggar was selected to start in place of Rhys Priestland.
