British and Irish Lions

Injured captain Jonathan Humphreys is replaced by Pontypridd hooker Mefin Davies, while the three other switches are all among the backs.

Former Leeds rugby league star Iestyn Harris wins promotion off the bench and starts at inside-centre instead of Tom Shanklin - while Craig Morgan takes over from injured wing Mark Jones, and Llanelli scrum-half Dwayne Peel is preferred to Gareth Cooper.

Cardiff flanker Martyn Williams will take over from Humphreys as captain, leading Wales for the second time in the tournament - having previously done so in the defeat against Scotland three weeks ago.

If Wales lose then they will suffer their first championship whitewash since 1995.

Wales Team: R Williams (Cardiff); C Morgan (Cardiff), M Taylor (Swansea), I Harris (Cardiff), G Thomas (Bridgend); S Jones (Llanelli), D Peel (Llanelli); I Thomas (Llanelli), M Davies (Pontypridd), G Jenkins (Pontypridd), R Sidoli (Pontypridd), G Llewellyn (Neath), C Charvis (Swansea), M Williams (Cardiff, captain), D Jones (Llanelli).

Replacements: G Williams (Bridgend), M Madden (Llanelli), S Williams (Northampton), G Thomas (Bath), G Cooper (Bath), T Shanklin (Saracens), M Watkins (Llanelli).

Assistant coach Graham Rowntree says The British & Irish Lions will have to be fully focussed to avoid a potential banana skin when they face The Barbarians a week today.

Three former British & Irish Lions will line-up against an England XV at Twickenham Stadium on Sunday as the Barbarians warm-up for their showdown with the 2013 tourists in Hong Kong next week.

Lions skipper Sam Warburton says the lessons he and his Welsh colleagues learnt in Australia last summer will stand them in good stead for their return visit with Britain and Ireland's elite next month.
