Wales head coach Wayne Pivac has continued to tinker with his starting XV as he makes four changes to the side that lost to France at the Principality Stadium two weeks ago.
Two of the changes see players returning to fitness after missing all of the Six Nations so far, with Josh Navidi and Liam Williams coming straight back in to start after recovering from hamstring and ankle injuries, respectively.
They replace Taulupe Faletau, who drops to the bench, and the injured Josh Adams in the starting XV, with Navidi wearing eight and Williams lining up on the wing, rather than slotting straight back in at their preferred positions of flanker and full-back.
The other changes appear to be tactical as Rob Evans gets the nod at loosehead prop and Tomos Williams is recalled to start at scrum-half, with Wyn Jones and Gareth Davies both missing out on the 23 altogether.
Rhys Carre will continue to provide loosehead cover and Rhys Webb is chosen as back-up scrum-half after making his Bath debut last weekend. The other change on the bench sees Aaron Shingler covering second row rather than Will Rowlands.
Dan Biggar and George North both sufficiently recover from knocks to maintain their spots in the starting XV, while Wayne Pivac continues to resist the urge to select Louis Rees-Zammit in a matchday 23.
