Gethin Jenkins has recovered from his calf injury to be named on the bench and, in one of three changes there, he joins fellow Blues players Sam Warburton, who covers the back row, and centre or wing Tom Shanklin.

“Jonathan brings over 50 caps of experience to the tight five and offers us some extra mobility around the field,” said Wales coach Warren Gatland.

“Leigh is a recognised right wing who offers us an extra kicking option and his return to full fitness after limited training in the run up to the England game allows his selection.

“We think we have a very strong bench with the right mix of players each able to make an impact if called upon and are pleased to be able to name Gethin although he will undergo further fitness assessments later in the week.

“Tom Shanklin returns to provide another 65-caps worth of experience as cover for the backs and Sam Warburton comes in as back row cover with JT (Jonathan Thomas) now having been nominated as a starting second row.”

Ryan Jones captains Wales for the 21st time taking him to joint fourth in the all-time list alongside Gareth Thomas and behind Rob Howley and Colin Charvis (22) and Ieuan Evans (28).

And fellow back row forward Martyn Williams reaches two more landmarks, winning his 93rd cap, to put him in third place on the all-time appearance list behind Charvis (94) and Thomas (100), and making his 49th tournament appearance – a Welsh record – putting him in line to become only the eighth player to play 50 championship matches.

“We were all disappointed with the result last weekend but the good news for these players is that they have an opportunity now, just seven days after losing a game we all feel we could have won, to bounce back against Scotland,” added Gatland.

“The championship is by no means over and we are back home at the Millennium Stadium on Saturday looking to kick-start our campaign.

“This is a must win game for us and the Millennium Stadium factor will have a big part to play, as will the fans, and we are all very much looking forward to coming home.”

The facial injury suffered by Tom Shanklin in the victory over Samoa gives Davies his chance with Gatland otherwise reverting to the starting line-up chosen to face New Zealand in the Series opener a fortnight ago.

And in a positional switch Blues centre Jamie Roberts moves to outside centre to accommodate Davies at No 12.

In forward changes from the team who beat Samoa Scarlets hooker Matthew Rees replaces Osprey Huw Bennett and Blues flanker Martyn Williams returns for regional team-mate Sam Warburton, with Bennett providing cover from the bench.

In the backs Ospreys wing Shane Williams, Scarlets fly-half Stephen Jones and Blues scrum-half Gareth Cooper all return for Tom James (Blues), Dan Biggar (Ospreys) and Dwayne Peel (Sale Sharks) respectively, with Biggar the only one of the three not included as a replacement.

Uncapped Dragons flanker Dan Lydiate gets his first chance of the campaign joining Ospreys prop Duncan Jones and Blues second row Bradley Davies in providing bench cover for the forwards and Ospreys centre Andrew Bishop, called in to train with the squad on Monday after Shanklin’s injury was confirmed, completes the 22 to face the Pumas.

“Jonathan came on at inside centre on Friday (against Samoa) when Tom (Shanklin) was injured and he acquitted himself well,” said Gatland.

“That’s his natural position, he plays there for his region and is comfortable there. Jamie is the more experienced player and more than capable of playing at 13 and we are looking forward to the continuation of the partnership from the second half last weekend.

“With James Hook going so well at full-back it was important for us to continue his international development in that position.”

Wales face a Pumas side ranked consistently higher in the IRB World rankings in the last 12 months – only in February, March and June did Wales temporarily go ahead before Argentina reclaimed the superior position – and who currently lie one place higher at seventh.

Attendance for the heavyweight clash, which has seen Welsh sides win seven times in 11 attempts, has already surpassed the 50,000 mark as Gatland prepares his men for battle on a brand new Millennium Stadium surface.

Gatland, who has rotated his bench with the aim of giving everyone in his small squad game-time, added:

“Dan (Lydiate) has impressed in training, we have selected a small squad and he is the only one who has not been involved so far, so we felt it was important for his development that he gets the opportunity to win his first cap and put what he has learnt into practice.”

Ospreys star Dan Biggar starts at 10 for Wales

Wales have made five changes to the starting line-up who faced New Zealand last Saturday for the visit of Samoa to the Millennium Stadium in the Invesco Perpetual 09 Series clash on Friday night (Kick-off 7.30pm).

Ospreys fly-half Dan Biggar wins his fourth cap when he starts at half back with Dwayne Peel (Sale Sharks), who will be playing in his 70th international for his country.

Biggar made his debut against Canada in 2008 when both he and Peel joined the game from the bench and he figured twice on Wales’ recent summer tour to North America, where he partnered the Blues’ Gareth Cooper in the win over Canada and again came on as a replacement alongside Peel against USA.

In the third back division change, Blues wing Tom James replaces Shane Williams.

Up front Huw Bennett (Ospreys) starts at hooker with Matthew Rees (Scarlets) moving to the bench and Blues back row Sam Warburton comes in for regional team-mate Martyn Williams.

Stephen Jones, Cooper and Shane and Martyn Williams miss-out all together with the Scarlets trio of Martin Roberts, Jonathan Davies and Morgan Stoddart providing cover for the backs from the replacements bench.

Front row cover is supplied by Rees and Ospreys prop Craig Mitchell, whilst fellow Osprey Jonathan Thomas and Blues second row Bradley Davies are also included.

“We’ve named a strong side and shown the maximum amount of respect to Samoa,” said Wales head coach Warren Gatland.

“They have proved to be a difficult side for Welsh teams in the past and we don’t expect the standard to be any different on Friday night.

“They are a tough physical team with players featuring for some of Europe’s top sides and there is no question of us under-estimating what we are up against.

“Dan Biggar is a bright prospect and his performances at the Ospreys this season mean he fully deserves his opportunity. Dan is surrounded by experience with Dwayne Peel and Jamie Roberts on either side of him which should help further smooth his transition to international rugby.

“Tom James has another chance to show us what he can do and Sam Warburton has been knocking on the door for some time after impressing the coaches on tour to North America this summer.

“But elsewhere we have maintained a consistency in selection and we will be looking to put a performance in on Friday night that will help create the momentum to finish of this series with wins and build on what we achieved for large parts of the game against New Zealand.”
