Wales boss Warren Gatland has sprung a major selection surprise by omitting established centres George North and Nick Tompkins from his line-up for Sunday’s Guinness Six Nations clash with France.

But Wales assistant coach Mike Forshaw says both players have “jumped back on the horse” after being left out, with a new midfield pairing of Joe Roberts and Owen Watkin preferred.

While North and Tompkins have 155 caps between them – North is Wales’ most experienced Six Nations squad member – 23-year-old Scarlets centre Roberts will make his first tournament start and Watkin is recalled after featuring against opening opponents Scotland.

“I think it is an opportunity to have a look at Joe,” Forshaw said. “I think Joe was unlucky not to go to the World Cup.

“We just felt if we were going to have a look, this was the game to do it. He (Roberts) is a really promising young 13 going forward, and Owen Watkin has a lot of experience.

“I suppose there is always a risk in every selection, but I suppose we have to be confident in the messages we are giving and the coaching we are doing.

“They (North and Tompkins) are not injured. Nick and George have been spoken to. They firmly believe in what we are doing.

“I don’t think they have been dropped. They have had two games together and they have done extremely well.

“But we have got to see Joe playing, and we are going to see him. We’ve decided to make that switch this week, and we’ve got to back him.”

Wales have lost their last four Six Nations games against France, but they tackle a struggling Les Bleus team defeated by Ireland and one that drew at home against Italy either side of narrowly beating Scotland.

Wales, though, have yet to win in this season’s competition ahead of their final two fixtures against France and Italy, which are both at the Principality Stadium.

Forshaw added: “The two boys were disappointed, but this morning they jumped back on the horse and they were very supportive of Owen and Joe. George is a great man around this environment, and he totally gets it.

“I would be disappointed if they weren’t disappointed. Selection day is always tough because you want to be in the team, you want to play for Wales.

“This morning they were both great. They were down yesterday, which I get because I have been there and know what it is like, but the two boys who have come in they will fully support them.

“It’s just finding out what the next World Cup cycle is going to look like in material and personnel. I think at the end of this tournament we will have a good idea who is going to Australia (on Wales’ summer tour) and then going into the autumn.”

Elsewhere, Wales captain Dafydd Jenkins has been switched from lock to blindside flanker, with Will Rowlands called up as Adam Beard’s second-row partner, while hooker Ryan Elias replaces Elliot Dee.

It will be Jenkins’ first appearance in the number six shirt for club or country, and he takes over from Alex Mann.

Rowlands missed Wales’ opening Six Nations appointment with Scotland after his partner gave birth, and he then featured off the bench in defeats to England and Ireland.

Mann is among the replacements, where his colleagues include fellow Cardiff forward Mackenzie Martin, 49 times-capped Dee and Scarlets scrum-half Gareth Davies.

“I don’t think it is a risk with Daf at six,” Forshaw said. “He is around two very smart back-rowers.

“Will Rowlands played 70 minutes on the weekend in Paris (for his club Racing 92). I saw glimpses of him getting back to his best. I think it is a good fit for us this week.”

Mike Forshaw has predicted a “ferocious 80 minutes” when Wales look to maintain their unbeaten Rugby World Cup campaign on Saturday.

Wales qualified for the quarter-finals with victory over Australia 12 days ago, and they need a point against Georgia at Stade de la Beaujoire to finish top of Pool C.

Argentina or Japan await in the last eight, with Wales heading to Marseille as firm favourites to secure a World Cup semi-final spot for the third time under head coach Warren Gatland.

Georgia, though, evoke painful memories for Wales, having suffered a shock 13-12 home defeat against them during last year’s autumn internationals.

Twelve of Gatland’s World Cup squad were involved that day, while four players from the starting line-up 11 months ago feature again – Louis Rees-Zammit, George North, Tomos Williams and Gareth Thomas.

“We are expecting physicality from them – they have always been renowned for a good pack of forwards,” Wales assistant coach and defence specialist Forshaw said.

“They have got some very dangerous backs, and they are a team that is growing. We will have to be at our best to get what we want to get out of the game tomorrow.

“This group has been pretty tough. We’ve gone about our business, and We have respected the opposition in this group – we’ve had to tough some results out.

“We expect them to be very tough to break down, and we have talked about ways around that. It is going to be a very physical game, Georgia are a very physical team.

“Whoever comes next, we will prepare exactly the same, whether it’s Argentina or Japan, two very proud nations.

“In the short term, tomorrow is the big goal for us. We are expecting a ferocious 80 minutes in a very hot stadium.”

Georgia are already out of the tournament following defeats against Australia and Fiji that sandwiched a draw with Portugal.

And while they will undoubtedly test Wales physically, the game represents another opportunity for Wales to showcase their rich vein of form.

Lock Will Rowlands added: “There have been some ups and downs the last few years, but everyone in this squad was confident we are a better team than we have shown at points.

“We wanted to come into this World Cup and just keep getting better and deliver performances we can be proud of and the Welsh public can be proud of.”

Wales only avoided propping up the Six Nations table last season by defeating Italy in Rome, underlining how impressive the transformation has been.

Gatland said: “The boys are implementing the game-plans we have put together outstandingly well.

“They have clarity about what they are trying to do and trying to achieve. I have been really impressed with their attitude, their focus and the way they have gone out and performed in the games.

“I thought one of the most pleasing bits against Australia was that we gave away less than 10 penalties. It was nine penalties, and we had nine turnovers in the game.

“When you are playing a quality side like Australia and you only have nine turnovers and nine penalties you give yourself a pretty good opportunity to win the game.

“As a squad I think we are in an outstanding place at the moment in terms of the morale in the squad and the banter that is going on behind the scenes.

“There is a lot of mickey-taking when it is required – not just the players, but the coaches as well. There is a really nice balance between hard work and having fun.”
