Marcus Smith was ruled out of England’s World Cup semi-final against South Africa because of concussion, head coach Steve Borthwick has confirmed.

Smith has been replaced at full-back by Freddie Steward after he took a series of blows in the last-eight victory over Fiji that resulted in him finishing the match with a bandaged head and fat lip.

A tackle by wing Vinaya Habosi forced him to undergo an HIA which he passed, but he failed the subsequent return to play protocols and has been stood down for Saturday’s Stade de France showdown.

England have made two further changes to their starting XV with prop Joe Marler and lock George Martin coming in for Ellis Genge and Ollie Chessum respectively.

“Marcus was unavailable for selection due to the return to play protocols. He was ruled out earlier in the week,” Borthwick said.

“He took a knock in the game and passed the first parts of the HIA process, which meant he finished the game.

“Then there are subsequent parts of the HIA process and one part of that he did not pass. And then it was confirmed to me he was unavailable for selection.

“He is perfectly fine in terms of symptoms – he doesn’t feel anything. We’d expect him to be available for selection after this weekend. It’s right to reiterate that player welfare is critical and vital to us.”

Whether a fit Smith would have been retained at 15 is unknown, but it appears unlikely given the precision and variety of South Africa’s kicking game.

Smith offers a cutting edge in attack but Steward is one of the game’s most accomplished full-backs – ultra-dependable under the high ball, strong in defence and a key component of England’s kick-chase.

Captain Owen Farrell is aware of the aerial onslaught coming in Paris but is backing Steward to thrive.

“The thing about Freddie is everybody knows how good he is in the air, everybody knows what a fantastic player he is in general,” Farrell said.

“But it’s the want to do it, the want to be in those battles, the want to go and get the ball back for his team, the want to defuse what’s coming our way. He is one of the best in the world at it.

“The kicking game has been a massive weapon for South Africa for years and years now. They’ve progressed it and they go on with a lot of contestable kicks.

“We’ve done our work and we’ve come up with our plan to negate what we can from them but also looking to be able to attack ourselves.”

The adjustments to the tight five see Marler’s scrummaging prowess get him the nod ahead of Genge, with Borthwick noting that South Africa have the “best scrum in the world”.

Martin will bring physicality to the second row while Genge and Chessum will take their place in England’s answer to the ‘Bomb Squad’ – the heavyweight forward reinforcements that the Springboks summon from the bench.

South Africa this week rejected the suggestion that in their quarter-final victory over France they used HIAs to rotate forwards Mbongeni Mbonambi, Pieter-Steph Du Toit and Duane Vermeulen, enabling them to take a rest.

Director of rugby Rassie Erasmus has a reputation for taking an innovative approach to the laws and testing their boundaries, but Borthwick has faith in the officials to spot any mischief.

“We have got a match officials team that’s world class, led by Ben O’Keeffe,” Borthwick said.

“I am sure everybody around the pitch as well will have every bit of process in place. There is no issues there from our perspective.”

Head coach Ian Foster has warned New Zealand the past counts for nothing as they head into their World Cup semi-final against Argentina as overwhelming favourites.

The three-time champions have lost just two of 36 matches against Los Pumas and are widely expected to prevail again in Friday’s crunch clash at the Stade de France in Paris.

“There are two teams in the semi-final – anyone can win,” said the All Blacks boss. “That’s the first mindset both teams have.

“We are massively respectful of Argentina. We know that they have had a great tournament.

“We don’t live in the past in terms of results. Rugby World Cup tournaments are really about the present. It’s about the best team on the night.

“If you go into a World Cup semi-final with any expectation that the past is going to happen again, you have got problems.”

Foster has made two changes to his side following the hard-fought 28-24 quarter-final win over Ireland, with Samuel Whitelock coming into the second row and Mark Telea starting on the left wing.

Foster said: “We’ve been really impressed with Argentina. We’re playing a team that we know scrap and fight for every little bit of possession. We are going to have to be at our best.”

Argentina overcame a 10-point deficit to beat Wales last weekend and reach the semi-finals for a third time.

Coach Michael Cheika has recalled Gonzalo Bertranou at scrum-half in his one change to the line-up.

“The history is not in our favour, but it is up to us to change that,” said Cheika, who oversaw a famous win over the All Blacks in Christchurch last year.

“We have a chance to on Friday and we will be ready. When we arrive on the field we will do what we do best.”

England second row Ollie Chessum insists revenge is not a motivating factor for Saturday’s World Cup semi-final against South Africa.

The rivals collide for the sixth time in the tournament’s history with the most recent of those meetings taking place in Yokohama four years ago when Eddie Jones’ side were toppled 32-12 in the final.

Having demolished New Zealand a week earlier, England were expected to topple the Springboks but instead they were off the pace from the start and overwhelmed as a consequence.

There should be at least eight survivors from that starting XV who take the field for the rematch at Stade de France, but Chessum denied there was a score to be settled.

“It hasn’t been mentioned much, certainly by me anyway. I wasn’t here in 2019 so it doesn’t motivate me,” the Leicester second row said.

“We have got a new group of players now who are quite happy to leave that in the past and focus on what we can do as this new England group.”

Predictions of the semi-finals being comprised entirely of Six Nations sides have failed to materialise with England the sole European representative and the only unbeaten team left in the competition.

They face one of the great South Africa sides who have been installed as strong favourites to emulate New Zealand by winning back-to-back World Cups in the wake of their victory over France in the previous round.

Defence coach Kevin Sinfield has said that England were “in awe of the physicality they brought” against the hosts and Chessum insisted the Springboks must be matched in the forward exchanges.

“These are the games you want to be a part of – against the biggest teams on the biggest stage in the biggest competition,” Chessum said.

“They have some unbelievable players in their pack. They bring an exceptional level of physicality. It’s up to us to go out on the weekend and compete against that.

“South Africa are unbelievable across the board and we have got to be the same, if not better.

“We are definitely hoping for another step from us. That’s been the nature of the competition. Week by week we have grown as a group and got better in various aspects of our game.

“It’s important that we bring the physicality, but also the level of execution as well.”

England have a settled team and will make only minimal changes to the starting XV that overcame Fiji in the quarter-finals.

The biggest area of debate is at full-back where Steve Borthwick is weighing up the high ball and positional expertise of Freddie Steward against the cutting edge in attack provided by Marcus Smith.

Smith, a converted fly-half, has made only two starts and three replacement appearances in the position and his lack of experience could be exposed by South Africa’s accomplished kicking game.

Owen Farrell’s impressive display against Fiji appears to have brought his duel with George Ford for the number 10 jersey to a conclusion, but Kyle Sinckler could return at tighthead prop.

Captain Antoine Dupont has declared himself “fully ready” to lead France in Sunday’s World Cup quarter-final against South Africa as he prepares to return to the starting XV just over three weeks after a broken cheekbone had him fearing his involvement in the tournament was over.

The 2021 world player of the year underwent surgery after going off injured following a head-on-head tackle from Namibia captain Johan Deysel in Les Bleus’ third pool match in Marseille on September 21, leaving the host nation fretting about their talisman’s availability for the remainder of the competition.

After resuming full training this week, Dupont has satisfied medics and coaching staff that he is ready to start Sunday’s box-office Stade de France showdown with the world champions.

“I feel very well,” said the 26-year-old scrum-half, speaking at Les Bleus’ team announcement press conference at Roland Garros on Friday.

“At the time, I didn’t know how serious the injury was so I thought the competition was over for me.

“I had to wait to get my hope back. I was lucky enough to have several weeks to rejuvenate and repair and have a full training week with the group.

“Today I am fully capable to be ready for this game on Sunday.”

Dupont admitted coming through training unscathed this week was a big thing for his mindset as he dismissed any suggestion that he has been rushed back into action ahead of schedule.

“It was quite progressive,” he said of his return to play. “I started low-intensity running and went up and up – and the same with contact. I started in the middle of last week.

“This week I was able to train fully and get back into game and contact situations which enabled me to get my confidence back.

“I’m fully ready and fit and had no pains. It was important to validate each stage of my recovery.

“I didn’t feel any pressure from the staff. It all happened quite naturally.

“I have the surgeon’s approval. Nothing was forced. We have all been working for four years to get to this stage so not to play with the handbrake on is the main thing.

“I knew if I wasn’t able to play, I would be replaced.”

Dupont has been experimenting with various forms of facial protection since his injury and he confirmed on Friday that he would wear a scrum cap against South Africa.

“It’s the surgeon’s wish, he suggested it,” said the captain. “Actually, he more than suggested it! I tested a scrum cap this week and it doesn’t bother my vision so I will be wearing it.”

Dupont has no concerns about returning to action against arguably the most physical nation on the planet.

“In these games there will always be a little bit of pain either physically or mentally,” he said. “Every time we play against big nations and when the stakes are high, they are always hard and physical.

“We need to be ready to suffer. We have high goals. We know it will be very hard and if we’re not ready for that, then I don’t think we’re ready for where we want to get to.”

Head coach Fabien Galthie was content that Dupont was fit enough to play.

“We treated the subject in a very relaxed way,” he said. “We were comfortable because we had some time and never pushed things. We took things step by step. Antoine has had time to recuperate.”

France have not lost on home soil since Scotland defeated them in a Six Nations match behind closed doors two-and-a-half years ago. Galthie is relishing the challenge of trying to prolong that run by ending the Springboks’ defence of the Webb Ellis Cup.

“To play such an opponent, who are world champions and beat the (British and Irish) Lions, they’re a team that’s all conquering and a team that inspired us a lot,” said the head coach.

“For us, what’s at stake is to simply play rugby with pleasure as a team and with ambition. We want to meet this challenge as we always have done.”

Conor Murray believes New Zealand’s loss is Ireland’s gain as “world-class” trio Bundee Aki, Jamison Gibson-Park and James Lowe bid to give their native country serious cause for regret.

Centre Aki, scrum-half Gibson-Park and wing Lowe will face the All Blacks at the Rugby World Cup for the first time after being selected to start Saturday’s quarter-final showdown in Paris.

The three New Zealand-born backs qualified for Ireland on residency grounds and have become key performers for Andy Farrell’s side, including helping secure a landmark tour success over the Kiwis last summer.

Murray expects their personal circumstances to provide an extra edge to their performances at Stade de France.

“Those three boys are so important to our squad,” he said.

“What they did, taking the chance to come over here and start a new life for themselves and prove themselves, all three of them have really done so.

“They’re three world-class players who we’re really going to rely on heavily and have performed unbelievably well in this competition.

“It hasn’t really been mentioned, the New Zealand thing. They’re part of our Irish team now and they’re really important to us.

“I’m sure there’s a part of them, that little bit extra that they want to get one over on their place of birth but they’re fully part of our Irish squad now.”

Gibson-Park and Lowe each represented the Maori All Blacks prior to their respective moves to Leinster, before winning maiden Ireland caps in 2020.

Connacht player Aki made his Ireland debut in 2017 but missed Ireland’s last-eight World Cup loss to New Zealand in 2019 through suspension.

The 33-year-old, who four years ago was sent off against Samoa – his parents’ native country, has been one of the standout performers in France.

“I hate saying it but he’s been playing the rugby of his life,” Murray, who lost his starting role to Gibson-Park, said of Aki.

“He can come across as a bit of a messer or jolly fella but behind the scenes Bundee is incredible.

“The level of detail, he’s always on the computers and always trying to figure things out, so he’s actually a smart fella, believe it or not.”

Ireland’s tens of thousands of travelling fans celebrated each of their Pool B wins with rousing renditions of ‘Zombie’ by Irish band The Cranberries.

“Bundee thinks they’re singing ‘Bundee, Bundee’,” Murray added. “They’re definitely not!”

Munster number nine Murray has 111 Ireland caps, is a veteran of three British and Irish Lions tours and is playing at his fourth World Cup.

The 34-year-old, who will begin on the bench against the All Blacks, is preparing for the biggest game of his career as his country strive to reach a maiden semi-final.

“It would mean everything,” he said. “On the outside it’s obviously a talking point that we’ve never got there and within the group we think this is a different team and the capabilities are different.

“This weekend is the biggest game I’ve ever played and it’s the same for everyone in the group.

“To get through that would be a huge, huge moment; a huge milestone.

“Breaking the quarter-final isn’t something we talk about. But with the special group we have, it’s something we’re chasing and would absolutely love to do for ourselves and the fans here and at home.

“I can’t get away from how hard it’s going to be, how difficult a task it is, but it would mean the world to all of us to get to that next stage.”

Murray has lined up 14 times against New Zealand for Ireland and the Lions.

He has scored four tries across those outings, including in his nation’s maiden success over the All Blacks in 2016 in Chicago.

“I’ve played against the All Blacks where we’ve beaten them, but when we play (again) they’re a completely different animal,” he said.

“When I started off my international career playing against New Zealand was really daunting and it still is, but did we really expect to beat them is questionable, whereas now there’s definitely a bit more belief.”

Ireland propelled themselves to the cusp of the Rugby World Cup quarter-finals with a gripping 13-8 win over reigning champions South Africa on a raucous evening in Paris.

Mack Hansen’s try and five points from Johnny Sexton helped settle a thrilling clash between international rugby’s top two teams at a sold-out Stade de France.

Replacement fly-half Jack Crowley added a late penalty as Ireland stretched their winning run to 16 matches to take control of Pool B.

Andy Farrell’s men also retained top spot in the global rankings ahead of the defeated Springboks, who now have work to do against Tonga next week to avoid early elimination.

Cheslin Kolbe’s second-half try and a Manie Libbok penalty kept Jacques Nienaber’s side in contention before they ultimately fell short in a nail-biting finale.

Pre-match talk was dominated by South Africa’s bold call to name an imposing seven-one split of forwards and backs on their bench – a decision head coach Nienaber called a “calculated risk”.

Ireland impressively defused the so-called ‘Bomb Squad’ to bring the knock-out rounds within touching distance.

Both sides arrived in the French capital with back-to-back wins on the board.

An estimated 30,000 Irish fans were expected among a capacity crowd for one of the most eagerly-anticipated group-stage matches in World Cup history.

That approximate figure seemed on the low side amid deafening noise in Saint-Denis further fuelled by a frenetic start of big hits and end-to-end action.

Ireland initially began on the front foot but, following a bold decision to kick for the corner, failed to capitalise on a couple of promising line-outs before falling behind to a Libbok penalty.

The set-piece struggles persisted and only some dogged defensive work, including Bundee Aki’s crucial tackle on Jesse Kriel, stifled the Springboks.

Farrell’s men continued to show plenty of attacking enterprise and were rewarded in the 33rd minute when sustained pressure led to Hansen capping a sensational team move by crossing on the right.

Captain Sexton calmly slotted the extras to ensure the Six Nations champions ended a breathless opening period of ferocious physicality 7-3 ahead.

Ireland have had the upper hand in this fixture in recent times, including a 19-16 Dublin success in November, but South Africa – tournament winners in 1995, 2007 and 2019 – hold a vastly superior World Cup record.

The unrelenting pace resumed following the interval and, amid further line-out issues, Ireland’s deficit was almost cut to a single point when Faf de Klerk’s penalty from halfway struck a post.

Yet South Africa seized on the loose ball from that missed kick and penned back their opponents before Kolbe touched down on the left to put his side 8-7 in front.

Fly-half Libbok was off target with the conversion and Ireland snatched back the lead going into the final 20 minutes thanks to a Sexton penalty.

South Africa turned to their stacked bench, including introducing Jean Kleyn, who represented Ireland at the last World Cup, in a bid to make the difference.

Irish indiscipline was in danger of proving expensive, with those in green relieved to see Libbok and then De Klerk squander further penalties.

The Springboks enjoyed the better territory and possession in the second period.

But Ireland, helped over the line by three points from Crowley, doggedly hung on to make a major statement moving towards their Pool B finale against Scotland in a fortnight’s time, while leaving the title holders with plenty to ponder.
