The British and Irish Lions' clash with the Sharks is in doubt after a member of their management team tested positive for coronavirus, while South Africa's game with Georgia is off.

Warren Gatland's men are due to face the Sharks in the second match of their tour of South Africa on Wednesday.

However, four members of the touring party, including two players, are now isolating having been deemed to be close contacts of the individual who had the positive test result.

Kick-off has been pushed back to 20:00 local time (19:00 BST) pending the results of PCR tests for the rest of the touring party. The game will go ahead should those tests return negative results.

"We have followed all necessary precautions since the start of the tour, which included regular testing and rigorous COVID-19 counter measure planning and protocols," said Ben Calveley, managing director for the Lions.

"Our priority is to ensure the health and safety of the entire touring party, which is why we quickly isolated the players and staff upon receiving the news of the positive result.

"Everyone has subsequently been lateral flow and PCR tested. The Medical Advisory Group await the results of the PCR testing in order to make a decision on tonight's game.

"The five individuals affected will be monitored closely during isolation and receive the best possible medical attention as we await the results of their PCR tests."

The Springboks' second Test with Georgia was cancelled due to COVID outbreaks in both camps.

South Africa's playing and management group returned 12 positive tests this week, with Georgia returning four. 

Jurie Roux, CEO of South Africa Rugby, said: "In the context of the loss of life and economic damage that COVID and this third wave are wreaking, the cancellation of a rugby match is pretty trivial.

"But it is still a major disappointment for the many stakeholders who have invested so much time, energy and resources into making these matches happen.

"I especially feel for the fans and players, and for our visitors from Georgia who travelled here at relatively short notice to take on the series, which has now been cut short. We've not been able to interact with them because of the bio-secure environments, but I'd like to thank them publicly for their support.

"We continue to plan for the Springboks' re-emergence from isolation and the completion of the Test series but in the short term we wish a speedy recovery for those who have been infected."

The Lions' clash with the Bulls on Saturday is already off and, while they are scheduled to face South Africa 'A' next Wednesday, the remainder of the tour now looks to be in question.

South Africa have recorded a further 10 COVID-19 cases, including head coach Jacques Nienaber, while the British and Irish Lions' match with the Bulls has been postponed.

A Lions statement on Tuesday confirmed they were exploring a rescheduling of the match or finding different opponents after five positive tests meant it was "impossible" for the Bulls to field a team.

The Lions' meeting with the Sharks in Johannesburg next Wednesday is set to go ahead as scheduled.

However, the Springboks' match with Georgia next week is also in doubt after Nienaber, five management figures and four players - Marvin Orie, Frans Steyn, Handre Pollard and Frans Malherbe - all returned positive tests.

There were also four cases of the virus within the Georgia team. Jurie Roux, CEO of South Africa Rugby, said the news underlined the problems posed by the Delta variant of the virus, which was first identified in India but has since spread to numerous countries.

"These positive results are a setback and have underlined the danger of transmissibility of the Delta variant," he said.

"The Springboks' second Test against Georgia is now in serious doubt, but we will wait for the MAG to consider the data and we will make the final decision tomorrow [Wednesday].

"The priority is to maintain the integrity of the Test series and we will continue to focus on that."

On Monday, South Africa suspended training and placed their squad in isolation after lock Lood de Jager tested positive for coronavirus.

There had been three further confirmed cases of the virus within the squad on June 27, although they were still able to go ahead with their first warm-up match against Georgia, which ended in a 40-9 victory for the Boks.

It was their first match since winning the World Cup in November 2019.

The first Test with the Lions is due to take place on July 24 in Cape Town, before moving to Johannesburg for the second and third matches.

The British and Irish Lions are focused on delivering a strong showing against the Sharks on Wednesday rather than uncertainty over their schedule due to the coronavirus.

Warren Gatland's side thrashed Johannesburg's own Lions 56-14 in their opening tour match at Ellis Park on Saturday, Josh Adams helping himself to a four-try haul.

Tom Curry, Josh Navidi and Adam Beard will now make their Lions debuts, while Iain Henderson takes over as captain for a midweek showdown with the Sharks at the same venue.

Sam Simmonds comes in for his first international start in over three years, but it is once again COVID-19 cases rather than selection that has dominated the pre-match talk.

The Springboks suspended training on Monday after Lood de Jager tested positive for the virus, with the players forced back into isolation.

Positive cases in the Bulls camp have put Saturday's match in doubt, but Lions defence coach Steve Tandy said they are taking a flexible approach.

"We'd weigh up if we need to give the boys a day off, if we need an internal match or a heavier loaded contact day," Tandy said when asked about plans if the Bulls game is called off.

"Through COVID, I think you learn you need to adapt. You can have the best laid plans, but things move really quickly and change - it's just be prepared for whatever comes our way at whatever moment in time. Whatever the group needs, more contact, an extra day off for recovery - we'll just adapt that as we go."

Phepsi Buthelezi returns t0 lead the Sharks at number eight, while Khutha Mchunu takes Wiehahn Herbst's place in the front row.

SIMMONDS DETERMINED TO GRASP HIS CHANCE

Simmonds has continued to be overlooked by England head coach Eddie Jones despite producing consistently outstanding performances for Exeter Chiefs.

The number eight, comfortably the leading try-scorer in the Premiership last season with 21, is determined to show he belongs on the Test stage.

"When you are starting you really get the opportunity to show what you can do and hopefully put what I have been doing in the last year or so into a Lions jersey," Simmonds said.

"As soon as I got selected for the Lions squad that was my sole focus – to push everyone here, to push to try and get as many games as I can and as a team the ultimate goal is to win the Test series in South Africa."

GATLAND WANTS BACK ROW TO PUT ON SHOW

New Zealander Gatland is excited to see what the back row he has selected can serve up in the second tour match.

"There's a huge amount of competition in the back row and I spoke to them all last night and just said, 'Look, you've got a licence from me to get your hands on the ball'," coach Gatland said.

"I want them to express themselves. I said they are probably not renowned as lineout experts but you have to play to your strengths, and they are strong defenders and great ball carriers.

"It's a different aspect to look at, but it's exciting and I’m really looking forward to seeing how they go as a trio. If you look at those players they are strong defenders, exciting ball carriers."

British and Irish Lions: Liam Williams, Anthony Watson, Elliot Daly, Bundee Aki, Duhan van der Merwe, Dan Biggar, Gareth Davies; Mako Vunipola, Luke Cowan-Dickie, Zander Fagerson, Iain Henderson (captain), Adam Beard, Josh Navidi, Tom Curry, Sam Simmonds.

Replacements: Ken Owens, Rory Sutherland, Tadhg Furlong, Tadhg Beirne, Jack Conan, Conor Murray, Stuart Hogg, Chris Harris.

Sharks: Manie Libbok, Werner Kok, Jeremy Ward, Marius Louw, Thaakir Abrahams, Curwin Bosch, Jaden Hendrikse; Khwezi Mona, Fez Mbatha, Khutha Mchunu, Ruben van Heerden, Hyron Andrews, James Venter, Thembelani Bholi, Phepsi Buthelezi (captain).

Replacements: Kerron van Vuuren, Ntuthuko Mchunu, Wiehahn Herbst, JJ van der Mescht, Reniel Hugo, Dylan Richardson, Grant Williams, Anthony Volmink.

Key Opta facts

- The Sharks and the Lions met in 2009, with the tourists winning that match 39-3. Lee Mears, Mike Phillips, Luke Fitzgerald, Lee Byrne and Jamie Heaslip all crossed for tries.
- The Lions have won 10 of their 11 fixtures against the Sharks/Natal, the exception being a 3-3 draw back on the 1924 tour.
- The Sharks had a 50 per cent win rate in the recently concluded Rainbow Cup SA (W3, L3), beating the Johannesburg-based Lions twice and the Stormers once.
- Following their victory over the Lions, the tourists are now unbeaten in their past five matches (W3, D2). That is their best run since winning six in a row in a run that spanned the 2009 and 2013 tours.
- The Lions are yet to miss a kick at goal so far in 2021, with Dan Biggar having slotted four from four and Owen Farrell landing all eight.

South Africa suspended training on Monday and again placed their entire squad in isolation after lock Lood de Jager tested positive for coronavirus.

It is the second time the Springboks have been forced to take preventative measures ahead of their upcoming series with the British and Irish Lions.

Vincent Koch, Herschel Jantjies and Sbu Nkosi tested positive for COVID-19 on June 27, though the world champions resumed training and their first warm-up match – a 40-9 victory over Georgia – went ahead as planned last Friday.

However, this Friday's game against the same opponents is now in jeopardy following another positive case, which also raises further questions about the three-match Test series with the Lions.

A statement from SA Rugby on Monday read: "Springbok training has been suspended for Monday following a positive test for COVID-19 in the squad.

"The players have been placed in preventative isolation prior to further PCR testing and a review of the testing data by the Medical Advisory Group (MAG).

"Lood de Jager returned a positive outcome in scheduled testing and, because of his close contact with a number of squad members, the entire group has gone into isolation.

"An update will be issued following the review by the MAG and the further testing."

South Africa's victory over Georgia was their first match since winning the World Cup in November 2019.

Their first Test with the Lions is due to take place on July 24 in Cape Town, before moving to Johannesburg for the second and third matches.

Tom Curry, Josh Navidi and Adam Beard will make their British and Irish Lions debuts against the Sharks on Wednesday.

The Lions will be captained by Iain Henderson for the first time, as Conor Murray has been named among the replacements for the midweek game at Ellis Park.

England flanker Curry and Wales duo Navidi and Beard will refresh the pack along with Sam Simmonds, who is set to make his first international start for over three years.

Josh Adams will play no part after the wing scored four tries against the tourists' South African namesakes the Lions on Saturday, playing a starring role in a 56-14 rout.

Lions head coach Warren Gatland said: "Wednesday night is another chance for us to have a look at a few more combinations.

"I'm looking forward to seeing how the back row goes; it's an exciting mixture and one that we hope will offer something a bit different.

"We expect another physical test against a side who are known for their power play and ambition.

"My congratulations to Tom, Josh and Adam ahead of their first starts in a Lions jersey."

Lions team to face the Sharks:

Liam Williams, Anthony Watson, Elliot Daly, Bundee Aki, Duhan van der Merwe, Dan Biggar, Gareth Davies; Mako Vunipola, Luke Cowan-Dickie, Zander Fagerson, Iain Henderson, Adam Beard, Josh Navidi, Tom Curry, Sam Simmonds.

Replacements: Ken Owens, Rory Sutherland, Tadhg Furlong, Tadhg Beirne, Jack Conan, Conor Murray, Stuart Hogg, Chris Harris.

Warren Gatland could not find too much to complain about after the British and Irish Lions made a brilliant start to their tour of South Africa, but says his team will not be 100 per cent satisfied.

Gatland's team beat the Lions 56-14 on Saturday, with winger Josh Adams running in four of their eight tries. 

Their points tally was the most in a match since they beat a combined New South Wales–Queensland Country 64-0 in 2013 – it was also their largest margin of victory since that match.

They are now unbeaten in their last five games (W3 D2), their best run since winning six in a row across the 2009 and 2013 tours.

Though content with how the tourists started their trip – in a match which was played behind closed doors – Gatland insists he has instilled a mentality of never being satisfied.

"You cannot complain. We've been getting better and better as a squad the more time we spend together," the former Wales coach said.

"We've put down a bit of a marker but as a group we won't be 100 per cent satisfied, there are still lots of improvements but we feel we can get there and makes lots of improvements too.

"The bench brought some energy but we had to adjust the way we wanted to play because they didn't pressure us as much with the blitz that we had expected, so we changed the way we played and that was a pretty good reaction.

"I was just really pleased with the energy out there, the guys working hard when they made a few breaks. We made a few mistakes and they were hard to get the ball off, but it was a really positive start."

Welshman Adams was the star of the show, as he became the first player to score four tries for the British and Irish Lions since Shane Williams went over five times against Manawatu in 2005.

Adams, who made five clean breaks in this game – the first player to do so since Williams managed six against South Africa in 2009 – has now scored a try in each of his last five games for Wales and the Lions combined.

"I thought the guy on the left wing did okay today," quipped Gatland.

Three debutants marked their British and Irish Lions bows with tries and Josh Adams added four in a dominant 56-14 win over the Lions in Johannesburg.

In their first tour match since landing in South Africa, Warren Gatland's men were comfortable from the outset thanks to the first contributions from Louis Rees-Zammit and Hamish Watson on Saturday.

Ali Price crossed for a third try before the break – the sixth first-half effort across two matches, already as many as the British and Irish Lions had in the entirety of the 2017 tour to New Zealand.

The scoring was not slowed by the interval, as a quartet of Adams finishes continued his own impressive form ahead of the South Africa Tests and Gareth Davies also got a breakthrough try from the bench.

Chris Harris, another of the four new faces in the XV, was heavily involved in a rapid start from the touring side.

His chip found Rees-Zammit, who was too quick and strong for his opponents and able to race through, and one try quickly became two as Watson barged under the posts.

The pace of the game slowed a little thereafter, but the hosts were caught dozing as Price dashed in following a long line-out throw.

A powerful run from Vincent Tshituka got the Lions on the scoresheet and they remained just about in touch at the break as a Wyn Jones try was chalked off due to foul play from Courtney Lawes.

It was only a temporary setback as Adams was through almost straight from the restart, although Francke Horn soon found space to feed Rabz Maxwane for a Lions riposte.

Finn Russell's pinpoint kick found a leaping Adams for another try and the British and Irish Lions picked off their tiring opponents.

Davies added his name to the scoresheet soon after his introduction and then Adams was twice left all alone on the left wing, completing his hat-trick and then getting a fourth.

Starting in style... again

The British and Irish Lions have now won their first game after arriving in South Africa on seven consecutive tours. The prior six victories came by an average margin of 23 points.

This triumph came as little surprise then, with the travelling side having lost only one of their past 57 tour games in South Africa – excluding Springboks Tests.

Louis looks the part

Rees-Zammit is still only 20 but has seamlessly adapted to each step in his career so far, becoming Wales' youngest try scorer in eight years against Georgia last November.

His British and Irish Lions bow was typically assured, helped by the early link-up with Gloucester team-mate Harris.

Chris Harris says the British and Irish Lions are "looking sharp" as they head into the first match of their South Africa tour.

The tourists face South Africa's own Lions, the Johannesburg-based team, on Saturday at Ellis Park.

Warren Gatland's team have a proud record to uphold, with the British and Irish Lions having won their first game after arriving in South Africa on each of their last six tours there.

Those victories have come by an average margin of 23 points –with their last such defeat a 9-6 setback in 1955 against Western Transvaal.

Scotland back Harris is set to make his debut for the visitors tomorrow as a much-changed team attempt to build on last weekend's win over Japan at Murrayfield.

The British and Irish Lions have never played the Lions previously but have taken on the affiliated Golden Lions, Johannesburg’s provincial side, and won each of their last four such games, most recently dishing out a 74-10 thrashing in 2009.

Only once have the travelling Lions won more heavily in South Africa, when dishing out a 97-0 thrashing to South Western Districts in 1974.

"It's an absolute honour to be puling on the jersey for the first time," Harris said on Friday. "I'm absolutely buzzing.

"It's pretty surreal to go from playing at university and working my way up through Newcastle and then representing Scotland, and this is just amazing to be able to pull on that jersey.

"I'm looking forward to it and it's a challenge I'm willing to relish. We got off to a really good start against Japan, but we're here to hit the ground running here in South Africa with another win.

"It's a new team, new combinations, but we've had a good week or two training together and we're looking sharp."

Scotland skipper Stuart Hogg will captain Gatland's team and was described as "a brilliant leader" by Harris.

"But he's also got plenty of brilliant leaders alongside him to help him along the way," said Harris, who will partner England skipper Owen Farrell in the midfield. "I think it will be a good game for him to start his captaincy as a Lions player."

Alun Wyn Jones was due to captain the Lions but was unable to make the tour after dislocating his shoulder against Japan.

His fellow Welshman and near-namesake Wyn Jones believes the British and Irish Lions being largely isolated in a team hotel while in South Africa need not be a hindrance.

"You've got to make it to your advantage," Jones said. "We're a close team now and I think the bubble's brought us closer. We spend a lot of time together and that can only be an advantage. We're having a good time together despite not being able to leave the hotel."

RUSSELL OUT TO MAKE AN IMPACT

The battle for the starting Test fly-half role is on, with Finn Russell the latest to get the chance to persuade Gatland he should play from the off in the first Test on July 24 in Cape Town.

Dan Biggar seized his chance last time out, being named man of the match against Japan, and Farrell is a contender for the role too, but Russell is certainly in with a strong shout, and these tour matches are opportunities to deliver persuasive performances.

It should help Russell to have Scotland team-mate Ali Price at scrum-half, and Hogg as skipper.

EARLY CHANCE TO PROVE PACK'S STRENGTH

The visiting Lions can expect a robust welcome to South Africa, and Gatland will look for his team as a whole, not least the forwards, to show they are up for the battle ahead.

Prop Jones is keen to make an early impact and said in Friday's news conference: "We know what South Africa bring. They'll be a big pack and every team we face out here there'll be a big front five.

"As a prop, it's a challenge that I'm looking forward to and I can't wait to get into."

British and Irish Lions: Stuart Hogg (captain), Louis Rees-Zammit, Chris Harris, Owen Farrell, Josh Adams, Finn Russell, Ali Price; Wyn Jones, Jamie George, Kyle Sinckler, Maro Itoje, Jonny Hill, Courtney Lawes, Hamish Watson, Taulupe Faletau.

Replacements: Luke Cowan-Dickie, Mako Vunipola, Zander Fagerson, Iain Henderson, Sam Simmonds, Gareth Davies, Bundee Aki, Elliot Daly.

Lions: EW Viljoen, Jamba Ulengo, Manuel Rass, Burger Odendaal, Rabz Maxwane; Jordan Hendrikse, Dillon Smit; Nathan McBeth, PJ Botha, Ruan Dreyer, Ruben Schoeman, Reinhard Nothnagel, Sbusiso Sangweni, Vincent Tshituka, Francke Horn (captain).

Replacements: Jaco Visagie, Sti Sithole, Carlu Sadie, Ruhan Straeuli, Emmanuel Tshituka, Morne van den Berg, Fred Zeilinga, Dan Kriel.

KEY OPTA FACTS

- Excluding their Test matches against the Springboks, the British and Irish Lions have suffered just one defeat in their 56 tour matches on South African soil since losing to Transvaal in 1968 (W54, D1), with the solitary defeat in that run coming against Northern Transvaal in 1997.

- The Lions won just one of their five completed matches in this year's Rainbow Cup SA (L4), against the Bulls in round four; their three games at Emirates Airlines Park saw an average of 66 points and nine tries scored per game (W1 L2).

- The Lions averaged the most carries (103) and passes (125) per game of any team in this year's Rainbow Cup SA, averaging 16 minutes and 35 seconds in possession per match, more than any other side; however, they gained the fewest metres (350) and beat the fewest defenders (19) on average.

- Finn Russell assisted 12 tries in the Top 14 for Racing 92 in the 2020-21 season, more than any other player in the league, and a competition-high four of those assists came from kicks.

- Sam Simmonds scored 21 tries for Exeter Chiefs in the recently concluded English Premiership, the most any player has managed for any side in an edition of the competition. He also topped the charts for carries (263), was the only forward to gain 1,000-plus metres, made the second most tackles (234) and beat the second most defenders (63) of any player.

The British and Irish Lions will repeat a feat last achieved back in 1959 if they avoid a series defeat in South Africa.

Warren Gatland's side drew with New Zealand four years ago after a 2-1 triumph in Australia in 2013.

It is 62 years since the Lions were able to avoid defeat in a third consecutive tour and they will have to face the world champions without Alun Wyn Jones, who was replaced as captain by Conor Murray after he suffered a dislocated shoulder in the win over Japan.

Confirmation on Sunday that three members of the Springboks squad have tested positive for coronavirus was a concern before the Lions boarded the plane to South Africa.

They are due to play five tour matches before the first Test against the Springboks at Cape Town Stadium on July 24.

Stats Perform picks out some of the standout Opta numbers for such an eagerly-awaited tour.

BOKS TO GO BACK-TO-BACK?

South Africa were 2-1 winners the last time the Lions toured in 2009, but they have not won back-to-back series since coming out on top in 1962 and 1968.

The Springboks have won eight, lost four and tied one of their previous series against the Lions.

South Africa can boast 23 victories to the Lions' 17, with six of the 46 previous showdowns ending in a draw.

There have been alternate winners in the past five series between the Lions and South Africa, a sequence the Lions will be hoping continues.

SOUTH-AFRICA-BORN FLYER AMONG DEADLY DEBUTANTS

While the loss of Jones and Justin Tipuric to injury in the win over Japan at Murrayfield were big blows, Gatland will have been encouraged by the performances of his debutants.

Three of the four try-scorers in Edinburgh were making their Lions bows, with Josh Adams, Duhan Van Der Merwe and Tadhg Beirne crossing.

South-Africa born Scotland wing Van der Merwe was the leading try-scorer in the Six Nations this year with six and beat 31 defenders in the tournament, breaking a record set by Brian O'Driscoll.

He can make a big impact against his country of birth along with Adams, the leading try-scorer at the 2019 World Cup with seven.

South Africa must also be wary of Louis Rees-Zammit, the youngest tourist aged 20, after he scored four Six Nations tries and had the most clean breaks (nine) in the competition, also gaining the most metres per carry (9.9m from 27 carries).

Beirne caught the eye against Japan and can play a big part in South Africa. He affected the most turnovers in the Six Nations with nine and was the first man to 87 rucks - the same number as Gregory Alldritt.

PASS MASTER MURRAY CAN DICTATE

Murray was surprised to be given the honour of skippering the Lions in the absence of the most-capped player in the history of international rugby.

The Ireland scrum-half has vast experience and can lead by example in his third Lions tour.

Murray has won two, lost two and drawn one of his previous Lions Tests and will look to pull the strings for the tourists.

The 32-year-old pivot has assisted 25 Six Nations tries, eight more than any other player, and holds the record for the most passes in the competition with 3,527. Peter Stringer is next on the list with 2,539.

KEY MEN CAN ROAR AGAIN

There were some outstanding performances in the Lions' tour of New Zealand as they drew 1-1 with the All Blacks.

Maro Itoje was among the heroes of that tour and the England lock will embrace the battle with the Springboks. He hit more rucks (162) than any other player in the Six Nations this year and amassed 16 turnovers.

Versatile back Liam Williams made the most metres by a Lions player on the tour in New Zealand four years ago with 344 from six games.

Gatland has been able to rely on Taulupe Faletau time and again over the years. The back-row made the most tackles (76) in New Zealand and beat more defenders (14) than any other forward.

It is nothing new for there to be uncertainty over what to expect for a British and Irish Lions touring party but the class of 2021 are well and truly stepping into the unknown.

Typically all the talk is over selection. Who starts at number 10? What will the make-up of the pack be, who gets the nod as the centre pairing or which wingers will be unleashed in the first Test?

Of course those questions are still to be answered, but when the Lions arrived in Johannesburg on Monday they were not only facing the challenge of trying to secure a starting berth.

A big surge in coronavirus cases has seen South Africa move into a 'level four' lockdown, with travel restrictions, an alcohol ban and an overnight curfew.

As the Lions were preparing to fly out on Sunday, it emerged that Springboks trio Herschel Jantjies, Vincent Koch and Sbu Nkosi had tested positive for COVID-19 - forcing training to be cancelled and the squad going into isolation.

They have since been given the green light to train and are set to face Georgia at Loftus Versfeld Stadium on Friday in their first Test since beating England in the 2019 World Cup final.

A lot of water has gone under the bridge since the drinks flowed as South Africa celebrated lifting the Webb Ellis Cup in Japan and they have a new head coach in Jacques Nienaber.

The world champions have also faced uncertainty, with the possibility of the Lions having home advantage or the series being staged in a neutral country before it was confirmed South Africa will host the tour.

While South Africa know they will not be entering the Lions den, Warren Gatland and his touring party are not certain where they might be heading just under a month before the first Test in Cape Town on July 24.

They are set to face a namesake in the Johannesburg-based Lions side, twice runners-up in Super Rugby, on Saturday as one the first of five matches in Gauteng but it is reported they could make further changes to the schedule.

The COVID situation has led to suggestions the entire three-match Test series could be played in Cape Town, with alternations to the fixtures having already been made last month.

Hostile crowds usually await the Lions, but they are set to face the might of the Springboks behind closed doors without an army of travelling fans to roar them on.

They must also go into battle without inspirational leader Alun Wyn Jones, ruled out due to a dislocated shoulder in the win over Japan at Murrayfield along with Wales team-mate Justin Tipuric.

A strong camaraderie will be needed more than ever, with Conor Murray promoted to skipper the side in the absence of stalwart Jones.

But there will be a lack of nights out as they are restricted to bonding in the bubble.

Gatland's men drew 1-1 with then-world champions New Zealand four years ago and can make it three series without defeat next month - a streak that has not been achieved since 1959.

They have the same head coach and key men who starred against the All Blacks, combined with exciting new faces such as South Africa-born wing Duhan van der Merwe and Louis Rees-Zammit.

Gatland may be unsure what challenges the Lions will face on and off the field before the opening Test but the wily New Zealander knows will know what to expect from a formidable South Africa side.

South Africa Rugby has announced the entire Springboks squad is self-isolating after three players tested positive for COVID-19 ahead of the Test series against the British and Irish Lions.

Following the discovery of the trio of cases during PCR testing in Johannesburg, the reigning world champions announced the cancellation of a planned training session on Sunday.

Team management will consult with medical experts before deciding what steps to take next, with the isolation of players and staff coming just as the Lions prepare to fly out from Edinburgh.

"The Springboks cancelled Sunday's planned training session in Johannesburg as a precautionary measure when scheduled testing protocols returned three positive COVID-19 test results when the team assembled on Saturday," a statement read.

"Three players tested positive for the virus following stringent real-time polymerase chain reaction (PCR) testing procedures on arrival at the team base.

"Team management immediately put the squad into self-isolation as a precaution until specialist medical advice is sought from the medical advisory group (MAG).

"A decision on further team activities will be made shortly.

"Director of rugby Rassie Erasmus emphasised that the team had followed all the necessary precautions since the start of the three-week conditioning camp hosted in Bloemfontein, which included mandatory COVID-19 testing three times a week, and that they would be led by specialist advice before any action is taken."

The Lions have had problems to deal with before departing for South Africa, captain Alun Wyn Jones suffering a dislocated shoulder during the warm-up win over Japan on Saturday that will see him miss the entire trip.

Fellow Wales international Justin Tipuric is another to be ruled out following the 28-10 victory at Murrayfield, with head coach Warren Gatland calling up Adam Beard and Josh Navidi as replacements.

Conor Murray, meanwhile, is to take over the captaincy duties in the absence of Jones, who was set to lead the squad on his fourth tour with the Lions.

The three-match Test series against the Springboks begins at Cape Town Stadium on July 24.

Conor Murray has spoken of his surprise at being named British and Irish Lions captain after Alun Wyn Jones was ruled out of the tour of South Africa.

Jones suffered a dislocated shoulder early in the Lions' win over Japan on Saturday, while Justin Tipuric also misses the tour due to a shoulder injury sustained at Murrayfield.

Warren Gatland turned to Ireland scrum-half Murray to take over as skipper, with Adam Beard and Josh Navidi called up as replacements for their Wales team-mates Jones and Tipuric.

Murray was not expecting to be asked to lead the Lions in what will be his third tour.

Asked if he was surprised Gatland wanted him to step up, the pivot said: "A little bit to be honest.

"I didn't even think about it. I knew that Al was out and then you look around the squad and there are so many contenders.

"Warren asked me just before the cap ceremony and it was surreal. I still don't have my head around it, but it's an unbelievable honour. It's something that I never thought would be possible.

"I didn't think about it long. I said, 'absolutely, it'll be a massive honour. Thank you very much for this opportunity'.

"Then you kind of think about how big it is and then obviously my phone has gone a bit crazy since it was announced.

"I tried to call my girlfriend Joanna, but her phone was on one per cent as usual. Her phone was off and my dad is in Edinburgh, he was out with his friends having a few drinks, and so he was the first person I spoke to.

"My mum's in Kerry and I rang her. She's down with a few friends who were watching the Japan game and they're celebrating too, so it still hasn't sunk in to be honest."

Murray said the loss of Jones is a big blow for the Lions.

"We're very disappointed to lose Alun Wyn. He's been brilliant for the first two weeks. I've known him from the past two tours and he's been incredible. It's a huge loss,” Murray said.

"He came up to me and said 'congrats and just be yourself' and I think that's really important. Growing up, you probably thought you had to try and be a certain type of person to be a leader, but you just have to be yourself.

"Once you have the respect of the group around you, that's a massive plus, a massive thing that can calm you down a bit. If you have the respect of the lads and you do what you do and you do it honestly, then it should be fine.

"It's a huge honour, but there's such a good group of leaders in this squad that makes it less daunting, definitely. There are lads that you can lean on, lads who have captained their country.

"There's massive experience there so you know it'll definitely be a group thing. I'm going to enjoy it and again lean on those boys. It'll take a bit of getting used to, but it's such an honour."

Conor Murray has been named as the British and Irish Lions captain for the upcoming tour of South Africa after injury ruled out Alun Wyn Jones.

Jones was ruled out of the tour, along with Justin Tipuric, on Saturday after he sustained a shoulder injury in the Lions' 28-10 win over Japan.

Irish scrum-half Murray, 32, has been handed the captaincy, with Lions head coach Warren Gatland bullish about his capability in Jones' absence.

"We’re all incredibly disappointed for Alun Wyn and Justin," Gatland said. "The timing of these injuries seem particularly cruel given we fly to South Africa tomorrow [Sunday], but unfortunately they’re part of the game.

"Alun Wyn will obviously be a big loss, both on and off the field, but will be ably replaced by Conor.

"Conor is an outstanding rugby player and is held in the highest regard with both the players and coaches.

"As a three-time Lions tourist, he knows what will be required as captain and I am certain he will lead the squad with excellence. He will also be well supported by an experienced leadership group."

Adam Beard and Josh Navidi have been added to the Lions squad to replace Jones and Tipuric.

British and Irish Lions captain Alun Wyn Jones has been ruled out of the tour of South Africa after suffering a dislocated shoulder in the 28-10 victory over Japan.

Jones had to be replaced in the eighth minute of the warm-up Test at Murrayfield on Saturday after sustaining the injury while being cleared out of a ruck as he attempted to get his hands on the ball.

Lions head coach Gatland confirmed after the match that Jones will not fly out to face the world champions.

The New Zealander said: "He's dislocated his shoulder.

"Prognosis of him being fit and very, very best-case scenario is the first Test [in Cape Town on July 24]. He's going to go and get a scan but we’re looking like we’re going to have to replace him."

Gatland added: "It’s pretty much made [the decision that Jones will not travel to South Africa], I was speaking to the physios, I’ve spoken to Alun Wyn.

"He understands, very best case scenario, he may get back for the Test but we need to call someone in and hopefully get them on the flight tomorrow.

"It's very disappointing, he’s been around rugby long enough, he's going to be gutted, I'm very disappointed for him. It's one of those things, you’ve got to put that behind you and move on as quickly as possible you can."

Gatland will consider who to replace lock Jones with in the squad and a new skipper.

He added: "We are discussing a couple of names at the moment, unfortunately I got called away to do a press conference.

"I'm going back to finalise that after I've spoken to you guys, we’ll make that call, have a discussion about who comes in and potentially who’s going to take over as tour captain as well."

Justin Tipuric also suffered a shoulder injury early on but Gatland is unsure of the extent of the damage.

The former Wales boss said: "It was a sting in the shoulder. We're going to check, to make sure there's no nerve damage.

"If there was nerve impingement that could rule him out - at the moment, pretty sure he’s going to be okay."

A hamstring injury sustained by Jack Conan will also be checked on.

Captain Alun Wyn Jones suffered an early injury blow before three British and Irish Lions debutants scored tries in a 28-10 defeat of Japan at Murrayfield.

Jones was withdrawn in pain in the eighth minute of the first-ever Lions Test in Scotland on Saturday with what was reported to be a shoulder injury.

Justin Tipuric was also forced off with an injury in the first half of the Lions' first meeting with Japan ahead of the tour of South Africa, which Warren Gatland's side won comfortably to lift the 1888 Cup.

Josh Adams, Duhan van der Merwe and Tadhg Beirne marked their debuts with a try, while Robbie Henshaw also touched down and the excellent Dan Biggar was on target with all four conversions.

Japan, playing their first Test since losing to the Springboks in the quarter-finals of the 2019 World Cup, entertained in the second half and were rewarded with a try from Kazuki Himeno.

There was concern for the Lions when skipper Jones was replaced early on after doing damage while trying to turn the ball over before his Wales team-mate Adams got the first points on the board.

The winger showed great feet and good strength to come in off the line and power his way over following a strong run from Bundee Aki.

Tipuric also made a concerning early exit before Van der Merwe caught Japan napping, picking the ball up from the back of a ruck and crossing all too easily.

The Lions were dominant and Ireland centre Henshaw ploughed over from close range after taking a pass from Conor Murray, with the impressive Biggar's third successful conversion increasing the lead to 21-0.

Courtney Lawes, Jones' replacement, lost control before grounding the ball when he crashed over early in the second half, but Beirne took a great line and showed a sharp turn of foot to burst through and go under the posts.

The Brave Blossoms enjoyed themselves after the break and Himeno finished following a lineout routine as the Lions defence work given a great workout with bigger tests to come.

Lions wait on Jones and Tipuric

It takes a lot to keep Jones down, so the sight of the lock grimacing on the deck and taking a rueful look to the skies was a worry for the Lions.

Gatland faces an anxious wait to discover the extent of the most-capped player in Test history's injury before the Lions board the plane to South Africa.

Flanker Tipuric's involvement was also brief just under a month before the first Test against the world champions in Cape Town.

Debut delight 

Wales winger Adams and Scotland flyer Van der Merwe wasted no time in marking their mark on their Lions bows.

Van Der Merwe, the leading try-scorer in the Six Nations this year, made 72 metres from eight carries and beat four defenders.

Adams did not see as much of the ball, but grasped his early chance, while Beirne made 49 metres from his 10 carries and won two turnovers in an eye-catching display.
