Fin Smith is a major doubt for England’s clash with Ireland on Saturday with Marcus Smith ready to step into the breach for the penultimate round of the Guinness Six Nations.

Fin Smith was the solitary member of Steve Borthwick’s squad to miss training on Tuesday as he recovers from a calf injury and with only Thursday’s main session left before the Twickenham showdown, time is running out to prove his fitness.

The 21-year-old fly-half has won his first two caps in his breakthrough season for England, coming on as a replacement for George Ford against Italy and Scotland, but could now slip out of the 23.

“We have tried to look after him the last couple of days and we are hoping he will be in full training on Thursday. We are looking after him,” skills and kicking coach Kevin Sinfield said.

If Fin Smith is unable to convince Borthwick on Thursday that he is capable of facing Grand Slam-chasing Ireland, Marcus Smith is available to take his place on the bench.

The Harlequins player missed the first three rounds of the tournament, also because of calf damage, but could even challenge Ford for a place in the starting XV if Borthwick decides significant changes are needed in response to the 30-21 mauling by Scotland.

“Fly-half is a position where we have plenty of strength so Steve will make that call on Thursday after the session. If everyone comes through on Thursday, Steve has obviously got a headache,” Sinfield said.

“To have Marcus available having not had him available throughout the Six Nations is a big boost for everybody.

“Not only with what he brings on the field, but off the field as well. He has got some bounce about him, a big smile and he loves being out on the training field. He has had a big impact this week.

“He comes in and is himself all the time so we missed him in those first few weeks. I’ve loved working with him and he’s an incredible talent. He can play, that boy.”

Borthwick names his team on Thursday afternoon and England’s head coach will be hoping for a response after the backwards step taken at Murrayfield.

The most damning statistic to emerge from a fourth successive Calcutta Cup defeat was the 25 handling errors made, a staggering number that prevented their attack from functioning.

“That was an anomaly for us. We certainly haven’t seen that throughout training at all,” Sinfield said.

“We’ve worked particularly hard in trying to understand why it happened. Some of it is difficult to understand.

“When you’re trying to understand why someone’s dropped a ball, or someone’s thrown a pass without looking where the pass is going, there’s a bit more to it than the numbers.

“We’re trying to understand the people, what they are feeling and what they are seeing at that moment in time. So we’ve delved pretty deep into that.

“We put some balls down in the Scotland game, why that is we’ll never know for sure. But what we have to try to make sure is that it doesn’t happen again.”

England are considering unleashing Manu Tuilagi against Scotland amid a warning from Kevin Sinfield that the midfield powerhouse remains a potent force.

Tuilagi is in contention to make his first appearance of the Guinness Six Nations at Murrayfield on Saturday, having been sidelined since December because of a groin tear.

It is the latest of many injury setbacks for the 32-year-old Sale Sharks centre, who broke his hand twice at last autumn’s World Cup, ruling him out of the start of the club season.

Tuilagi’s return would provide the ball-carrying muscle missing from England’s back line – Ollie Lawrence is also an option for the role – and Sinfield insists he still has plenty to offer the national side.

“I would say this without any doubt – don’t write him off yet,” the assistant coach said.

“He’s still got some really good years ahead of him and he’s very much a big part of how we move forward and what we are doing here.

“When you play like he has done for so long, and you are so physical, it is inevitable that at some point in your career you will have a run of injuries.

“What you find with the powerful-type guys, one injury tends to lead into another.”

Also back in contention for the pivotal round-three encounter in Edinburgh is George Martin, the star of England’s heartbreaking World Cup semi-final defeat to South Africa who is fully fit after tweaking his knee.

The 22-year-old enforcer, who can operate at lock or blindside flanker, stood toe to toe with the Springboks and his physicality will be a valuable asset against Scotland.

“Big. Physical. Aggressive. Great ball carrier and he’s one of our better defenders,” Sinfield said.

“In the semi-final he really stood out on the international stage against some of the biggest, nastiest, most aggressive forwards in the world. He was in and amongst it.

“If selected I have no doubt he’ll leave a mark on somebody. He’s already a top player, but he’s going to get better and better.”

England have won only one of their last six meetings with Scotland and visit Murrayfield knowing it is the most hostile of all opposition venues for Red Rose teams.

Fly-half George Ford has braced his side for a “niggly game” – he was targeted in the tunnel by Scotland number eight Ryan Wilson in 2018, sparking a brawl with Owen Farrell – and Sinfield insists frayed tempers are inevitable.

“There’s certainly going to be some niggle. When you’ve got two angry, nasty forward packs wanting to go at each other, there will be some niggle,” he said.

“It’s a Test match, there’s a lot at stake and we haven’t won against them for a number of years, so no doubt there’ll be some niggle.

“There will be some bits thrown at us over the next couple of days that we haven’t planned for or we haven’t quite expected.

“But that’s the nature of being in top-level sport and we meed to make the best of some of the circumstances we are faced with.

“The history is important for us to understand but it won’t change anything – we’re not going up there with any fear.

“We know how dangerous they are, we know they’re a good team, we know they’ve got some great players. But so have we.”

Kevin Sinfield is to step down as England defence coach after the summer tour to Japan and New Zealand.

Sinfield has been Steve Borthwick’s number two since the start of his reign in December 2022 but his time at Twickenham will come to an end after 18 months.

Before he moves on, the Leeds rugby league great will take charge of individual skills and work with the kickers having previously overseen the defence.

“Kevin after the World Cup had a period of reflection, like every member of the management team did,” Borthwick said.

“Kev’s decided that longer-term he’s going to head in a different direction away from the England rugby team.

“He’s going to work with the team through the Six Nations and through the summer tour.

“Ahead of the autumn series Kev will not work with the team then, he will move away from the team and in a different direction.”

When asked to expand on Sinfield’s future plans, Borthwick replied: “Not right now and Kev hasn’t told us. That’s a question you can discuss with Kev in due course.

“I’m just grateful that’s he added so much value over these 12 months and that he’s going to stay with the team for the Six Nations and the summer tour.

“Through this first 12 months, Kev’s role and what he’s added as we’ve reset the team, you can’t overstate the value he’s brought, what he’s done and the relationships he’s built.

“I’ve changed his role to skills and he will be working specifically on catch-pass skills with the kickers and goalkickers, which he does so very well.”

Kevin Sinfield will take some time to consider his next campaign after completing the latest energy-sapping fundraising challenge to help people living with motor neurone disease as the push to raise awareness and research for a cure goes on.

Inspired by former Leeds team-mate Rob Burrow, the 43-year-old pushed through a gruelling schedule of running seven ultramarathons in as many days in seven different cities around Britain and Ireland.

Sinfield, the current England rugby union defence coach, had again battled the elements en route to crossing the finishing line to a rapturous welcome on The Mall in London on Thursday afternoon.

The team had taken to the roads once again to raise awareness of MND and funds for five charities supporting people affected by the condition and their families, and also to fund research into effective treatments and ultimately a cure.

Each leg of his latest challenge comprised 27 miles – the conventional marathon distance with an extra mile added to signify how much further people can go to help friends in need.

On Thursday evening, the Motor Neurone Disease Association confirmed with online and other donations, Sinfield’s latest campaign had passed the £777,777 target.

Proceeds from the ‘7in7in7’ initiative will go to mainly to the MND Association and Leeds Hospitals Charity appeal to build the Rob Burrow MND centre in the city.

There will also be donations to the My Name’5 Doddie, the Irish MND Association, the Darby Rimmer MND Foundation and support for the 4ED campaign.

Although taking a well-deserved to reflect with his team on their achievements, Sinfield knows there remains plenty of hard work ahead in the continuing quest for a cure.

“I think we will see,” Sinfield said when asked what other challenges might be on the horizon.

“What I am really conscious of is the team have put so much into the last four that we have done and I can’t do it on my own.

“I know we are extremely passionate about what we have done. We have got some time together on the bus tonight, so we will let everybody settle and enjoy, to celebrate because it has been a really good week.

“I will never say never – there is a big possibility we will go again.

“I think some of that will show in what our grand total ends up being, because we are certainly all conscious of compassion fatigue.

“But we are also really conscious that we are really passionate about the MND community and how we can help it, whether that is through running or not, we are not sure.

“But we are really keen to see the donations and where those end up, because ultimately they are the things that really shift it.

“We want to raise the awareness, we want to change how people feel about the MND community.

“But if we are really going to help them, then we need to continue to raise money so that they can find a cure.”

Sinfield added: “Wherever we have been now, we have had unbelievable support, especially from the MND community, so that needs to continue in some way, shape or form.”

Former England bowler Stuart Broad and Rugby World Cup winner Will Greenwood were among the guests who joined Sinfield during the final leg in London, which had started at Twickenham.

With his latest campaign put to bed, it will not be long before Sinfield’s attentions turn swiftly back to his day job.

“I have got some work to do tomorrow and I will be at a game on Sunday (Sale v Stade Francais), but I will try to catch up on some sleep and I want to see some family,” Sinfield said.

“I was away for five months and then had a busy month getting ready for this, then away again for a week so I am really looking forward to Christmas.”

Kevin Sinfield was greeted by Welsh rugby union great Sir Gareth Edwards as he completed the latest of seven back-to-back ultra marathons in aid of research and support for those living with Motor Neurone Disease in Cardiff.

Sinfield was greeted by Edwards on the pitch at Cardiff Arms Park during half-time in the United Rugby Championship match against Scarlets, which the visitors won 29-23.

Afterwards Sinfield, whose latest fund-raising feat ticked over the quarter of a million pound mark in the course of its second day, hailed his welcome in the Welsh capital as one of the best he has experienced.

Speaking to members of the Cardiff squad, Sinfield said: “Over the last few years we’ve been to some pretty special places and we’ve run in some pretty amazing cities, but the welcome the team has had today in Cardiff has been as good as anywhere.

“Don’t under-estimate the friends you have in here, the bonds that you get playing rugby of either code is something that not many sports give you.

“Win or lose, there will come a point where you can’t play any more for whatever reason. You look after each other when you cross the line, and for the rest of your lives you need to look after each other as well.”

Sinfield’s fourth fundraising challenge takes him on to Birmingham on Sunday, beginning at Alexander Stadium and calling at St Andrews, Villa Park and Edgbaston before concluding in Centenary Square on Sunday afternoon.

He will then move on to undertake routes around Edinburgh, Dublin and Brighton, before concluding with a route that takes him up The Mall in London next week.

Since starting his ultra-marathon quest in 2020, the 43-year-old has raised over £8million to help fund research and help those with the disease, and he has vowed he will continue to undertake his marathon quest until a cure can be found.

Kevin Sinfield has stressed there is no time to waste as he prepares to embark on his latest “crackers” fundraising quest in aid of research into Motor Neurone Disease next week.

The former Leeds Rhinos star, who will set off another series of seven back-to-back ultra-marathons from Headingley Stadium on December 1, remains frustrated by a perceived lack of urgency on behalf of the Government to fulfill a pledge to commit £50million to fighting the disease.

The 43-year-old Sinfield and his team have raised over £8m from a number of endurance events which started with their first ‘7 in 7 challenge’ in 2020.

Sinfield said: “It’s really important that the money is released as promised and used in the best possible way so that we can find a cure.

“People with Motor Neurone Disease don’t have time to wait. We all want things done now, we all want change now, we all want our great scientists across the UK to work together to find a cure, so there is some frustration.

“We know the statistics from diagnosis are that 50 per cent die within the first two years. People with MND don’t have time on their hands, so we’ve got to shift this quickly. As we saw with Covid, if you throw money at something you can get a cure.”

“(Rob) thinks I’m crackers but he fully gets it. He’s with us 100% in spirit, and he’ll be there at the start and the finish. He’s such an inspirational friend and I’m delighted to be doing it again.”

Sinfield admits he will embarking on his latest quest a little “under-cooked” due to the tight turn-around following his return from France where he was working as a defensive coach for England’s rugby union World Cup squad.

Having insisted prior to a similar epic challenge last year that his running days would soon be a thing of the past, he revealed his ex-team-mate, good friend and inspiration, MND sufferer Rob Burrow, described him as “crackers” for resolving to put himself through it once again.

But Sinfield, whose route this year will include trips to Birmingham, Brighton, Cardiff and Edinburgh, as well as Dublin for the first time, said he never considered hanging up his running shoes while a cure remains out of reach.

“There are 100,000 reasons why we shouldn’t go again but there is one big reason why we should and that is to continue representing this beautiful community,” added Sinfield.

“The messages, the emails, the face to face meetings – on average three times a day someone will stop me and tell me someone they know has got MND or has passed, and they want us to keep going.

“The awareness is crucial and will make such a difference to finding a cure for this disease. It’s shown me why I’m here on this earth, and that’s to try and help. I don’t think there’s a greater gift.

“(Rob) thinks I’m crackers but he fully gets it. He’s with us 100 per cent in spirit, and he’ll be there at the start and the finish. He’s such an inspirational friend and I’m delighted to be doing it again.”

Following his first quest of seven marathons in seven days in 2020, Sinfield ran 101 miles in under 24 hours from Welford Road in Leicester to Headingley in 2021. Last year’s challenge ended on the pitch at half-time during the men’s World Cup final between Australia and New Zealand at Old Trafford.

The Government has been approached for comment about Sinfield’s concerns.

Kevin Sinfield will again push his body to the limit in support of friend Rob Burrow as he plans to run seven ultra-marathons in seven different cities across seven successive days.

Sinfield is taking on the challenge to raise money for motor neurone disease charities after seeing his great friend Burrow affected by the illness.

The former Leeds Rhino player, who has undertaken several other physical challenges over the last few years and raised £13million, will run 27.2 miles on seven successive days around the United Kingdom and Ireland.

He will start in his home city of Leeds on December 1, before heading to Cardiff, Birmingham, Edinburgh, Dublin and Brighton before finishing in London.

Sinfield said on BBC Breakfast: “We go again, we start three weeks on Friday, running has been a great vehicle for us.

“It has been a great way of celebrating the MND community and celebrating Rob and showing people we care. The support we have had has been amazing.

The plan is to run seven marathons, plus an extra mile each day, in seven different cities in the UK and Ireland across seven days.

“We are aware we have not been to the south and felt it is important to go to the south because there is a large number of people with MND down there, we wanted to go to Wales and Ireland.

“We want to share and support and raise some funds.

“We are really looking forward to it; there are 100 reasons we shouldn’t go again, but there are 5,000 why we should and the big reason is Rob.

“If we want to make a dent on MND and to shift the dial line we need money and the awareness has been brilliant over the last four years.

“It’s the funds (that) are going to make a difference, whether that is to find a cure, or to support families or provide equipment like Rob has where people can still communicate and be in the room.”

Burrow, who is able to speak using special equipment, told his friend: “Another crazy challenge, we thought you would stop after the last one, but here you go again. I would do the same for you.

“I hope to see you off at the start and be there at the finish, you never stop banging the drum for the MND community, remember Kev you aren’t getting any younger!”

Kevin Sinfield has demanded England’s players empty the tanks in Saturday’s World Cup semi-final against South Africa to ensure they are not left with lifelong regrets.

For eight of the starting XV it is the chance to avenge their defeat to the Springboks in the 2019 final when the expectations generated by a thumping victory over New Zealand a round earlier were ground into the Yokohama Stadium turf.

Steve Borthwick’s England were given little hope of challenging for South Africa’s crown due a dismal series of warm-up fixtures which extended their losing run to five defeats in six Tests, yet they are the only unbeaten side left in the tournament.

Defence coach Sinfield sees the benefit of continuing to confront adversity head on at the Stade de France.

“I am certainly not overwhelmed. I understand the challenge in front of us,” the English rugby league great said.

“But I don’t mind being backed into a corner, don’t mind being written off, don’t mind being slammed, don’t mind being in the thick of a pretty tough circumstance.

“I just think that we’re in a World Cup semi-final, there is a lot of good in us, there are a lot of things to be excited about.

“Coming up against South Africa will let us know where we’re at. But for our players, they are so excited to be out there.

“Rewind eight weeks to the end of August and it was pretty grim for us, but we want them to absolutely rip into it on Saturday night.

“We want them to give everything they’ve got, otherwise you end up with a load of regrets for the rest of your life.

“We are really looking forward to this – we are coming up against the best team in the world at the weekend.”

England have a mix of ages in their squad ranging from 22-year-old George Martin to 36-year-old Dan Cole and Sinfield believes that the final message to the squad before they take the field needs to be delivered with more subtlety in the modern era.

“It’s probably more subtle than Churchillian speeches and understanding that leadership has changed and this generation is different,” Sinfield said.

“Gone is the big Churchillian leader. They do exist but they’re quite rare.”

South Africa director of rugby Rassie Erasmus is adept at what Warren Gatland describes as “dark arts”, such as using mind games to give his side an edge.

The most recent example is the suggestion that the Springboks used HIAs in their quarter-final victory over France to give forwards Duane Vermeulen, Pieter-Steph du Toit and Bongi Mbonambi a rest – a claim denied by Erasmus.

Attack coach Richard Wigglesworth insists England are ready for any scheming but believe the match will be decided in other areas.

“I’m sure that, with the smarts of their coaching team, they will try to throw stuff at us, no doubt. Will that be the winning and losing of this game? Probably not,” Wigglesworth said.

“It will probably be the big bits of the game that decides that and then they’ll give those little nuances a chance.

“I wouldn’t like to guess what they are going to try and do because I know they will watch and hear everything we say. I wouldn’t like to try and give anyone a head start.”

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.

Marcus Smith is now viewed as a “world class” option at full-back by England after Kevin Sinfield was blown away by his defensive heroics against Fiji.

England are hopeful that Smith will be passed fit for Saturday’s World Cup semi-final against South Africa after he was placed on modified training alongside Jonny May, Manu Tuilagi, Tom Curry, Courtney Lawes and Dan Cole.

The converted fly-half ended the last-eight victory over Fiji on Sunday with a fat upper lip and bandage around his head after he was the victim of a dangerous tackle by wing Vinaya Habosi, forcing him to depart for an HIA which he passed.

Once again he is competing with Freddie Steward for the number 15 jersey and, after two starts in the position, Sinfield sees a player who has the bravery to match his attacking brilliance.

“We’d all agree he’s a world class 10, but last weekend I felt he was a world class 15 as well,” England’s defence coach said

“You’ve got to remember this guys has played around 100, 120 minutes as a full-back in Test rugby so far.

“What he’s done on the training field for us has been outstanding. You’re blown away by what he does now that he’s being given more time and space.

“If there was any doubt how brave and courageous he is then you saw it with your own eyes. The bloke got his face smashed in and threw his body into tackles.

“The guys are in full admiration for him – he’s just got his face smashed all over the place yet he wants the ball. He’s just a brave guy.

“And not just because he’s physically tough and brave, because to be put on a world stage in a quarter-final and deliver what he delivered was an absolute credit to him. What a great kid.”

Steward was dropped from the 23 against Fiji altogether and now England face the choice of reverting to his high ball and positional expertise or rolling the dice by retaining Smith in the hope he will provide a cutting edge.

South Africa possess a far smarter kicking game that could expose Smith’s inexperience at full-back, pointing to Steward’s likely return when Steve Borthwick names his team on Thursday.

“I’ve worked with Fred for some time now and thankfully I’ve not had to have many of these conversations where I’m trying to pick him up,” Sinfield said.

“Clearly he was disappointed, as anyone would be, missing out on a quarter-final, but he’s responded as we’d expect him to.

“He is a great lad, you know what he’s about, he works incredibly hard at his game, he cares and he is unbelievable full-back too.

“We are in a pretty fortunate position where we have three world class 10s and two world class full-backs.

“Our team has changed every game throughout the World Cup and Steve selects the team he thinks it will give us the best chance of winning that game.

“Just because Fred wasn’t selected last week doesn’t mean he does anything wrong, he has actually done a lot of great things and a lot of things right, but Steve and the coaching team thought it was the right thing to go with Marcus against Fiji.”

Kevin Sinfield fittingly kicked the winning points to provide a fairytale finish to his magnificent rugby league career as he led Leeds to Grand Final glory on this day in 2015.

The Rhinos twice came from behind in a pulsating tie against Wigan, with Sinfield converting a 64th-minute try from substitute Josh Walters to seal a 22-20 win at a sell-out 73,512 crowd at Old Trafford.

Sinfield’s third goal meant he ended his rugby league career on 4,231 points, making him the third highest scorer in the history of the game, as Leeds celebrated a seventh Grand Final triumph in a year where they also scooped the Challenge Cup and League Leaders’ Shield.

“To top my career off with a treble in my final year is unbelievable. I’m really thankful and really proud,” said Sinfield, who switched codes to rugby union and had a season with the Rhinos’ sister club Yorkshire Carnegie.

“To finish on an ending like that against a great team and for it to be so tough out there, to come through at the end was brilliant.”

Jamie Peacock bowed out with a record 11th appearance at Old Trafford, as well as a ninth success, while fellow front rower Kylie Leuluai maintained his 100 per cent record in Grand Finals in his last game with a sixth triumph.

Leeds’ hero was Danny McGuire, scoring two of their four tries which helped his side to a first win over Wigan in seven major finals and belated revenge for their defeat in the inaugural Grand Final in 1998.

“We were all a bit emotional and felt a little bit drained early on,” McGuire said.

“Three of my best mates are not going to be playing with me next year. Psychologically you try to put that to the back of your mind but it’s always there.

“You want to send them out on the best terms and fortunately we were able to do that through sheer determination and hard work.

“It’ll be weird not having the Sinfield shirt next to mine on a Friday night.”

Kevin Sinfield insists England do not have a discipline problem as they look to draw a line under their latest red-card setback that resulted in a two-match ban for Tom Curry.

England did not contest Curry’s dismissal for a dangerous tackle in Saturday’s 14-man demolition of Argentina when the Sale openside appeared before a brief virtual hearing on Tuesday.

After the disruption caused to their World Cup preparations by the Owen Farrell and Billy Vunipola incidents last month, England are keen to focus all their attention on Sunday’s Pool D showdown with Japan.

And while continuing to hone their tackle technique in training, defence coach Sinfield is satisfied there is no deep-rooted problem.

“Discipline-wise, we gave away seven penalties at the weekend,” Sinfield said.

“I don’t think we’ve got a discipline problem, I thought it was really unfortunate what happened at the weekend. It’s been different from the other challenges that have taken place.

“We continue to work on our tackle skill – and work incredibly hard. The guys have bought into it and have done so for some time, but they’re human and they make mistakes. We’ve got to understand that.

“And unfortunately we’ve had to deal with four red cards in six games. We’re getting pretty good at defending with 14 men, but we want to have our full complement on the field for as long as possible at all times.

“So we hope to improve that area, but it’s tricky to pinpoint exactly what that is.

“We’ll spend time with Tom and put him through tackle school and work incredibly hard with him again. We’ll get him right for a couple of weeks’ time.”

Observers have been left scratching their heads by the inconsistent refereeing evident during the opening round of World Cup matches.

While Curry was given his marching orders for his third-minute clash of heads with Juan Cruz Mallia, similar incidents involving players from South Africa and Chile went unpunished.

On this occasion England could be justified for nursing a sense of grievance at the way the cards have fallen against them and Sinfield admits the disparity between decisions makes a player’s job harder.

“I think it makes life really difficult for the players, first and foremost, and that’s what we’re all here for,” Sinfield said.

“We all want to see the players out on the field, we want to see the best players in the world go head to head. We’ve just got to be careful.

“We control what we can control. We’re in full support of the rules and regulations. We try and train as hard as we can, but within the laws of the game and we’ll continued to do that.”

England name their team to face Japan on Friday night and Sinfield insists there will be no room for sentimentality when making any tight calls.

“At the top of the list is to win the game to we pick the team that we think gives us the best chance of winning,” Sinfield said.

“Within that there’s always a balance, but we’re in a World Cup and we’re not here to give people game-time, we’re here to win games.

“We’re not here to give Test shirts out because someone deserves one, we’re here because we have to win games.”

Freddie Steward has revealed that England’s heroic defensive stand against Argentina was inspired by a blast from Kevin Sinfield that was delivered in the wake of their Fiji debacle.

Steve Borthwick’s team opened their World Cup campaign with a 27-10 victory on Saturday despite playing 77 minutes with 14 men after Tom Curry was shown a red card for a dangerous tackle.

It was England’s finest hour since Borthwick took over and it arrived just in time as, until that act of defiance at the Stade Velodrome, concerns were being raised over a defence that had leaked 30 tries in nine Tests.

A conclusive defeat by Fiji at Twickenham a fortnight earlier saw the team reach their lowest ebb – and Steward admits the players deserved the reaction from Sinfield that followed.

“We got a bit of a rocket after that game. There were no complaints about that, it needed to happen,” the Leicester full-back said.

“We had a very thorough review, which we needed, and we reaped the benefits against Argentina. It was necessary for that to happen.

“That’s what makes Kev such a good defence coach – he’s so inspiring. He motivates us so much and he’s the sort of bloke you don’t want to let down.

“That’s testament to him as a bloke. When you go out there, part of it is you do it for him.

“You don’t want to see a guy like that, who puts his heart and soul into us in his work with his defence, feel let down.

“Kev is big on covering each other’s backs. That’s his big thing. He wants a defensive unit that are going to work incredibly hard for each other and, when it goes wrong, cover up for each other.

“Inevitably, you can be as good a defender as you want as a full-back but there are going to be times where it doesn’t go to plan and that is where you get tested. That’s his main ethos.”

Now that England have successfully negotiated their biggest match since the 2019 World Cup final, they have been challenged by Sinfield to ensure their defensive masterclass in Marseille is not a one-off.

“It is just a start. We saw lots of what we had seen in training against Argentina, which is pleasing, but I still feel there is so much in this team – so much improvement, so much growth,” Sinfield said.

“To get the win, given the noise that has been around us and the way the group have really circled the wagons – metaphorically that is – is really pleasing.

“We saw a fight, a spirit and attitude that the people at home supporting us and in the ground would have loved to have seen, and for us as coaches that is particularly pleasing, (but) we know we need to be better.

“Part of our challenge as coaches and part of the challenge of the playing group is to ensure this is not an anomaly, it is the start.”

Curry faces a disciplinary hearing in Paris on Tuesday night when he is expected to learn the length of his ban for the dangerous challenge that led to a clash of heads with Juan Cruz Mallia.

Kevin Sinfield has revealed Marcus Smith is still an option at full-back as England look to ignite their attack.

Harlequins fly-half Smith injected energy and creativity into England’s game when appearing as a second-half replacement in the World Cup warm-up fixtures against Ireland and Fiji.

Head coach Steve Borthwick on Thursday names his team to face Argentina in their crucial Pool D opener, with Smith under consideration as support for starting 15 Freddie Steward.

“Marcus is a magician with the ball – step off both feet, quick, can beat the opposition for fun,” defence coach Sinfield said.

“So why not try to give him a bit more time and space than he would typically get at 10, try to get him a little bit wider?

“We have been working on it for some weeks now with him in training. He’s been incredible at the back.

“He embraced it straight away. It was a question that was posed to him. Have you ever played 15? His first answer was ‘No, but I would love to’.

“It would be crazy of us to put Marcus in the team and not try to put the ball in his hands, and give him space to attack. He’s a different attacking threat to Fred.

“Fred is 6ft 4in and 105kg, so he brings a different threat to Marcus when he carries the ball.”

Eddie Jones believes Steve Borthwick is well-equipped to succeed him as England coach.

A difficult 2022 bookended by Six Nations frustrations and a dismal November international period saw Jones let go less than a year before the World Cup.

Borthwick, who was an assistant to Jones with Japan and then England, has since taken the reins with his own number two Kevin Sinfield.

Reflecting on the appointment of his former colleague, the 62-year-old was effusive in his praise, adding that he takes pride in having helped to shape his path to the top job.

"Steve Borthwick was there [from 2016] until 2020," he told The Guardian. "He then wanted his own career.

"One of my jobs was to get England to win again, which I did, and also to produce the next head coach.

"So I look back with satisfaction because Steve will do a bloody good job. He's outstanding."

Jones, a famously outspoken figure within the game, departed last year after a tough period suggested his chances of repeating 2019's run to the World Cup final was a tall order.

The former Australia coach acknowledged he made errors, adding: "I don't have any regrets, but there were a couple of mistakes, a couple of decisions I probably rushed."

Asked whether his decision to criticise England's reliance on the public school system for players was such a call, Jones agreed in that assessment, though he defended his stance.

"That was one of my mistakes," he added. "Once you get that group offside you're in trouble. But diversity is so important and sport's not sheltered from that."
