James Hook is dropped to the bench for Wales’ quarter-final clash against Ireland.
Hook missed crucial penalties against the Springboks in the pool phase and has since dropped out of favour.
In other changes, Alun Wyn Jones and Jonathan Davies move from the bench to second row and outside centre respectively while Danny Lydiate and Shane Williams return to blindside flanker and left wing respectively from outside the 22 that beat Fiji 66-0 last Sunday.
Wales - 15. Leigh Halfpenny, 14. George North, 13. Jonathan Davies, 12. Jamie Roberts, 11. Shane Williams, 10. Rhys Priestland, 9. Mike Phillips, 8. Toby Faletau, 7. Sam Warburton (c), 6. Danny Lydiate, 5. Alun Wyn Jones, 4. Luke Charteris, 3. Adam Jones, 2. Huw Bennett, 1. Gethin Jenkins.
