Recently-appointed co-captain Rory Darge will start Saturday’s Guinness Six Nations match at home to France following six weeks out with a knee injury.

The 23-year-old Glasgow flanker takes over the number seven jersey from previous skipper Jamie Ritchie, who drops out of the 23 altogether, in one of three changes – all in the forward-line – to the team that started the 27-26 win away to Wales.

Darge, who has recovered quicker than anticipated from an injury sustained away to Edinburgh on the last weekend of December, is listed as co-captain alongside stand-off Finn Russell for the Murrayfield showdown with a French side aiming to bounce back from their chastening 38-17 home defeat by Ireland.

Number eight Jack Dempsey and lock Grant Gilchrist, who was suspended last weekend, return to the side in place of Luke Crosbie and Richie Gray, both of whom picked up tournament-ending injuries in Cardiff.

The backs department is unchanged, meaning Kyle Rowe, who made his first international start in Wales, continues at full-back in the absence of the injured Blair Kinghorn.

On-form Saracens back-rower Andy Christie has been named among the subs after missing out on the 23 last weekend.

Defence coach Steve Tandy insisted Scotland would have no concerns about throwing recently-appointed co-captain Rory Darge into Saturday’s showdown with France following six weeks on the sidelines.

The 23-year-old flanker sustained a knee injury while playing for Glasgow against Edinburgh on December 30 and has not played since.

He was initially rated doubtful for the entire championship but has recovered quicker than anticipated and is expected to be ready for this weekend’s match against Les Bleus.

Darge’s return to contention is particularly timely after fellow flanker Luke Crosbie and veteran lock Richie Gray were ruled out for the rest of the tournament with shoulder and bicep injuries respectively.

“Dargey’s trained and he’s looking good,” reported Tandy on Tuesday. “He came through training last week, he trained again today, so all being well in the rest of the training week he’ll be available.”

Asked if he felt Darge could slot straight back into the Test XV having not played for almost a month and a half, Tandy said: “Definitely. He’s done it before, after injuries.

“Knowing Rory and the guy he is, how diligent he is and how he looks at and studies the game, we have no doubts. Physically, it feels like he’s adding layer on layer as he gets a little bit older.

“He’s physically ready and even when they are injured, the boys are still lifting (weights) – it’s not as if they’re sitting there doing nothing. They’re active in and around what the strength and conditioning guys and the medical team want.”

Tandy lamented the loss of back-rower Crosbie and second-rower Gray after the pair – both of whom started the match – picked up tournament-ending injuries in Saturday’s 27-26 victory away to Wales.

“First and foremost, with the characters they are, they’re awesome individuals,” said the coach. “Richie brings lots of experience around the group and he’s got better with age.

“He’s great to work with and you see the energy and clarity he brings to the group. He will be sorely missed.

“Luke has fought so hard to get to the international scene. You see the warrior he is on the field, but there is also the character he is and how he leads in the training environment, how he speaks in meetings.

“We’ve got a great squad though. If you look at the back-rowers, there are loads of form players so we’re lucky enough to have an abundance in those positions.

“If someone misses out, everyone else is ready to step into the shirt.”

Tandy admitted there were “lots of learnings” for Scotland after a game in Cardiff where they went dangerously close to squandering a 27-0 lead.

However, he also felt there were plenty of positives to be drawn from their first win in the Welsh capital in 22 years, ahead of back-to-back home games against France and England.

“It’s important not to get too far ahead,” said Tandy. “We’ve had a really good result, going to Wales and getting that job done, but now it’s just about focusing on France.

“Coming back to Murrayfield is massive. We’ve got to improve bits of our game and continue lots of the stuff we did in the first half and at the back end of the Wales game.”

Scotland have suffered further injury woe after forwards Luke Crosbie and Richie Gray were ruled out for the remainder of the Six Nations.

Edinburgh back-rower Crosbie went off in the second half of Saturday’s 27-26 victory away to Wales with a shoulder issue, while Glasgow second-rower Gray was forced off in the first half with a bicep problem.

The injuries have now been assessed and Scotland confirmed on Tuesday morning that the pair – who both started in Cardiff – will be sidelined for the rest of the tournament.

Scotland were already missing some key players going into last weekend’s opener as co-captain Rory Darge was not deemed fit enough to feature due to a knee injury sustained at the end of December, while Toulouse full-back Blair Kinghorn and Edinburgh wing Darcy Graham were ruled out of at least the first two matches with knee and quad problems respectively.

The Scots are hopeful that Darge will be fit enough to return in Saturday’s Murrayfield showdown with France, which would offset the loss of Crosbie in the back row, while Edinburgh lock Grant Gilchrist is available after suspension to take the place of Gray.

Luke Crosbie revealed his pride at bucking the trend to emerge from a public school background and represent Scotland at a Rugby World Cup – but the flanker’s friends will ensure he never lets his success go to his head.

The 26-year-old Edinburgh back-rower grew up in the West Lothian town of West Calder, which is far from a traditional rugby heartland.

Crosbie’s love for the game, which he first got into while at primary school, has taken him to a level whereby – after winning five caps for his country – he is preparing to make his first appearance at a World Cup after being selected to start Saturday’s must-win match against Romania in Lille on Saturday.

“Looking at my journey to get here, it’s obviously special for me and my family that I’ve come right through,” he said.

“At school, I don’t think there was anyone who played rugby, we didn’t have a rugby team or anything like that.

“To reflect on that and be sitting here at a World Cup is special for me and obviously my family have seen me go through all the stages. I’m just really excited and proud to be here.”

Crosbie knows it is more difficult to make it in professional rugby in Scotland if not educated at a private school. His relatively humble beginnings in the sport, and those close to him, ensure he will always keep his feet on the ground.

“If you want something you have to go for it,” he said, reflecting on his rise. “At school this is what I wanted to do. But not everybody knew you could do this as a job.

“When I went back to school, they said, ‘what do you do for work, though, what’s your job?’ Which is fine, I quite like that.

“None of my friends know much about rugby at all so when I chat to them they don’t know what is going on.

“It could be the biggest game for Edinburgh or Scotland and they’ll be asking for a night out! And I’m like ‘you’re not following it at all, are you?’ Which is great. But it’s special for me and I’m just proud to be here.”

Crosbie was unavailable for the opening match against South Africa after suffering a rib injury in the build-up. Nonetheless, he has enjoyed his World Cup experience so far and is looking forward to his first outing on Saturday.

“Picking up an injury wasn’t great, but I’m totally fine now and I’m looking forward to the opportunity this weekend,” he said.

“I’m feeling really confident, the performances I have put in at Edinburgh throughout the season have been great. To get in the World Cup squad was great for me and my family.

“The support I get from my family is the same wherever I play. I could be playing a game for Currie at Malleny Park and they would be there.

“I played an Under-20 game in France for Scotland and my dad and uncle drove all the way down to watch my play. It doesn’t matter who I’m playing for, they’re always there supporting me.”
