Wales boss Wayne Pivac has backed Josh Adams to thrive as a centre of attention in Saturday’s Guinness Six Nations opener against Ireland.

Adams will make his first Test match appearance in the centre after 35 Wales starts as a wing.

Adams, who 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.

“He has trained there (outside centre) quite a bit, and it is something we are excited to have a look at,” Pivac said.

“We wouldn’t do it unless we thought he could do a job. He has played there for Cardiff.”

George North, who is among a number of injured British and Irish Lions currently unavailable to Pivac, made an identical switch with considerable success for last season’s Six Nations title-winning campaign.

Pivac added: “They are different players, but if he has any sort of impact like George, we will be very pleased.

“George hadn’t played there much either, and he made a pretty good fist of it.

“It is a position where you need a lot of pace, not only with the ball but also without it.

“Josh is strong in the contact area and a good defender. We are excited to see him go. Hopefully, the conditions are such that we can move the ball around and get it into his hands in good positions on the park.”

Saracens’ Nick Tompkins will partner Adams in midfield, while there are also starts for wing Johnny McNicholl and flanker Taine Basham, with uncapped Ospreys hooker Dewi Lake among the replacements.

Flanker Ross Moriarty, who has recovered from a shoulder injury suffered against New Zealand in October, is also on the bench and poised to win his 50th cap.

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.

Wales have claimed a solitary victory from their last seven visits to Dublin’s Aviva Stadium, and they will encounter an Ireland side fresh from toppling New Zealand just over two months ago.

“They (Ireland) are very powerful, aren’t they? They had a very good autumn,” Pivac said.

“They built on the last Six Nations and how they finished that competition, and they haven’t really looked back since.

“They are moving a bit more ball than they probably have in the past, which makes them a bit more dangerous. They have obviously got a power game they can use, but there is a bit more width in their game now.”

Pivac, meanwhile, revealed that Exeter forward Christ Tshiunza will miss the whole Six Nations after suffering a hamstring injury in national squad training on Tuesday.

Tshiunza, 20, won two caps as a replacement during the autumn.

Wales will return to Cardiff next week and an appointment with Scotland in the first of three Six Nations home games this season.

The Welsh Rugby Union has moved to curb alcohol-related disorder by ordering the bars to be closed during the second half of this year’s home fixtures against Scotland, France and Italy.

The decision came after the WRU addressed reports of anti-social behaviour during the Autumn Nations Series games earlier this term.

The WRU said a number of high-profile incidents, including two intrusions on to the pitch in consecutive games, were accompanied by some reporting of poor behaviour at the 74,000-seater venue.

Pivac said: “The incident (pitch intrusion) we are talking about against South Africa was when Liam Williams thought he had a pretty good chance of scoring a try. It is what might have been.

“We just want people to enjoy the game. For everyone to enjoy the game, we can’t have the odd idiot. That just spoils it for everyone.

“Get there nice and early, have some fun, but enjoy yourselves in the right way.”
