Josh Adams switches position for Wales opener against Ireland
Adams, who has won 35 caps and was top try-scorer at the 2019 World Cup, would have featured there in the Autumn Nations Series appointment with Fiji this season, but he suffered an injury during the warm-up and did not start.
But there is no place in the matchday 23 for centre Jonathan Davies, who has made 99 Test match appearances for Wales and the British and Irish Lions.
Fly-half Dan Biggar skippers the team as Wales start the tournament without world record Test match appearance holder Alun Wyn Jones.
Wales have claimed a solitary victory from their last seven visits to the Aviva Stadium, and they will encounter an Ireland side fresh from toppling New Zealand just over two months ago.
On Adams’ midfield selection, Wales head coach Wayne Pivac said: “It is something we’ve been thinking about for a while.
“He has done it in training and in small doses at the end of a game. We think this is a golden opportunity to answer that question.
“I am really pleased for Ross. We think coming off the bench he will make an impact, so that is why we’ve gone that way.
“Dewi is a big man, a very good rugby player. He is strong over the ball and gives us something in defence as well as his attacking prowess.
“History in Dublin shows it’s a hard place to go.
“They are a very tough, very physical side, so we know we are going to have to step up in that area of the game and make sure we do that for 80 minutes.
“We’ve got to be very disciplined, and as a result be in there fighting for the right result.”
