WALES have made one change to their starting line-up as they face a tough trip to unbeaten Ireland at the Aviva Stadium on Saturday.

Warren Gatland has kept the changes to a minimum after his side led for much of the game at Twickenham, with Sam Costelow returning at fly half.

Among the replacements, back-row Mackenzie Martin could win his first senior cap this weekend. If he comes on in Dublin, he would become the 1,200th Wales men’s international.

Tight-head prop Dillon Lewis would be making his first appearance of this Championship if called on from the bench.

“We are excited to go out to Dublin and test ourselves against one of the leading sides in world rugby. It’s a challenge we are relishing,” said Gatland.

“We’ve made steps in the last couple of games and now it’s about building on that, learning from those experiences and taking that into this weekend.

“It’s about continuing to work hard, looking for accuracy in our performance across 80 minutes and also keeping our discipline.”

Ireland are currently top of the Guinness Six Nations after a 38-17 win in France and a 36-0 win over Italy.

Ireland v Wales will be shown live on ITV and S4C. Kick off is at 2.15pm on Saturday, February 24.
