Prop Gethin Jenkins will captain Wales in Friday’s third-place play-off as Sam Warburton is unavailable due to suspension.
Warburton was banned for three weeks after being red-carded for a dangerous tackle in last Saturday’s semi-final. He will be replaced by Toby Faletau at openside flank, while Ryan Jones will come into the starting side at No 8.
Paul James replaces injured tighthead prop Adam Jones and Bradley Davies comes into the second row.
