Captain Sam Warburton returns to the Wales starting line-up for their game against Ireland on Saturday as one of three changes from the team that beat Italy last weekend.
Gethin Jenkins also comes back into the team, with Paul James dropping to the bench, from which he could win his 50th cap. Justin Tipuric also lines up amongst the substitutes.
Andrew Coombs starts in the engine room in place of Luke Charteris, who has been ruled out with a hamstring injury. There is no place for Jonathan Davies in the squad, as Jamie Roberts and Scott Williams continue their partnership in the centres and James Hook and Liam Williams remain the bench options.
“It’s great to bring Sam and Gethin back into the side and it’s a good opportunity for Andrew Coombs to start as well,” said Gatland. “Last weekend was a good hit out for a lot of reasons, but we still have things to work on and we know how important this game is.
“We haven’t lost an away match in the Six Nations since 2011 and we have to have the belief and confidence that we can do it again this weekend. It’s going to be tough, both sides won their opening game, we will have to be physical and take it to them.
“We feel in most tournaments we get stronger as it goes on and that will need to be the case this weekend.”
