Wales have made three changes to their side for the RBS 6 Nations clash away to Scotland on Saturday with Paul James (Bath), Alun Wyn Jones (Ospreys) and Sam Warburton (Blues) coming into the starting XV.
We have had two good, hard fought away victories but we know will have to be at our best again to come away from Murrayfield with the result
James will win his 44th test cap at Murrayfield and comes in to the side after Gethin Jenkins failed to recover from a calf injury picked up in the victory to Italy.
Jones and Warburton, who both featured from the bench in Rome after recovering from injuries, start in the second row and at openside flanker respectively.
Ryan Jones (Ospreys) who has led Wales to two successive away victories will again captain the side and will line up in the back-row alongside Warburton and Toby Faletau (Dragons) at No 8.
Alun Wyn Jones comes into the second row to partner regional team mate Ian Evans and in the front row James comes in to play alongside Ospreys duo Richard Hibbard and Adam Jones.
Wales and Scotland go into Saturday's match level on points in the RBS 6 Nations table with two victories apiece and the visitors will be looking for their fifth successive away victory in the tournament, a feat they haven't achieved before.
For the fourth match running, interim head coach Rob Howley has named an unchanged back line.
Mike Phillips (Bayonne) will continue his partnership at half-back with Ospreys fly-half Dan Biggar with Jamie Roberts (Blues) and Jonathan Davies (Scarlets) named in the centre. Leigh Halfpenny (Blues), Alex Cuthbert (Blues) and George North (Scarlets) make up the back three.
"We have had two good, hard fought away victories but we know will have to be at our best again to come away from Murrayfield with the result," said Howley.
"It's disappointing for Gethin to miss out but Paul has impressed and made an impact in each game he has played.
"We are bringing in a wealth of experience with Alun Wyn and Sam and they both performed well off the bench in Rome. Ryan has led the team to two wins and deserves to captain the side against Scotland.
"We have spoken a lot about momentum in this tournament and we go into the game with two wins under our belt but Scotland are in the same position and it's going to be a good challenge."
There are three changes on the replacements bench. Blues prop Scott Andrews comes into the match day squad to replace Paul James and Andrew Coombs and Justin Tipuric take their place amongst the replacements.

Glyncoch have had a remarkable past couple of seasons, having lost just once in the last two seasons. Their fine form has been capped by claiming the South Central Division 5 crown of the SWALEC League.
With two rounds of the HSBC Sevens World Series remaining, Wales head coach Paul John has sprung a few surprises for this week's penultimate round in Glasgow. And there's still plenty to play for with World Cup spots on the line.
