The skipper has left the squad to be with wife Louise for the birth of their third child.
Buttler produced an inspired performance in the second T20 at Edgebaston on Saturday, with his contribution of 84 from 54 deliveries helping the hosts to a 23-run victory.
The 33-year-old's knock, which included eight fours and three sixes, marked the second-highest score by an England captain in a T20I, behind Eoin Morgan's 91 against New Zealand in 2019.
However, the hosts will have to make do without their white-ball skipper in Cardiff, while he could potentially miss the fourth T20 at The Oval on Thursday and some matches at the T20 World Cup, which begins on Sunday.
Moeen Ali will captain England in Buttler's absence, with either Phil Salt or Jonny Bairstow set to deputise as wicketkeeper.
England will begin the defence of their T20 World Cup title against Scotland in the Caribbean on June 4.
Buttler succeeded Eoin Morgan as England's white-ball skipper earlier this year following the latter's retirement, having played a pivotal role in their 2019 World Cup success in the fifty-over game.
But a recurrence of a long-standing calf issue while playing in The Hundred has left him nursing a knock just weeks away from the start of this year's short-form tournament in Australia.
England will warm up with a mammoth seven-match series over the next fortnight against Pakistan, with Moeen handed the armband in Buttler's stead, and he has now revealed that he does not know if his team-mate will figure.
"We're not sure," he stated. "He did his calf in The Hundred. He's done it before, so he's just [being] a bit more careful. Maybe at the back end of the tour, he will play one or two games, but we're not sure yet.
"It depends on how he feels. Obviously, with the World Cup in Australia, he's huge for us, and we want him fully fit for the whole competition.
"There won't be any risking him. He will decide if he is going to play in maybe the last one or two games."
England's trip to Pakistan marks a historic series and a particularly special one for Moeen, who is of Pakistani descent, as he gets to lead out the side.
"With my roots being from here and to lead England in such a big and historic series, it's huge," he added. "It's a very proud moment for me and my family, my mum and dad and everybody.
"Of course my family are very happy and my friends and my community, and everybody who I feel like I represent they’re very happy for me. Captaining England in any game anywhere in the world is a huge honour."
England follow their tour of Pakistan with a trio of warm-up games against Australia, before they get their campaign underway against Afghanistan in Perth on October 22.
Pakistan won the ODI series thanks in large part to the brilliance of captain Babar Azam and his superb 66 propelled the hosts to a competitive 162-8 in Lahore.
Babar's composure at the crease was much-needed for Pakistan, who lost Mohammad Rizwan (23) and Fakhar Zaman (0) in successive balls to T20I debutant Cameron Green (2-16).
Adam Zampa finally drew a stray shot out of Pakistan's skipper, who picked out Nathan Ellis to leave his side on 118-4.
Having already dismissed Iftikhar Ahmed, Ellis – the pick of Australia's bowlers with 4-28 – then did the damage through Pakistan's middle order, getting rid of the dangerous Khushdil Shah (24), Asif Ali (3) and Shaheen Shah Afridi (0), though Usman Qadir's flurry of 18 not out boosted the hosts.
Travis Head quickly set about getting the tourists' chase on its way, scoring a rapid 26 that included four boundaries before he was sent packing by Haris Rauf.
Josh Inglis (24) kept up the pace until Qadir struck, but Australia seemed well set before Marnus Labuschagne, Marcus Stoinis and Green were dismissed in the space of 20 balls.
Yet captain Finch anchored the chase as he returned to form following back-to-back ducks in the ODI series, with his steady innings steering Australia into needing 15 runs from three overs.
A costly start to the 18th over from Haris saw McDermott plunder successive boundaries, though the pressure was back on Australia when Finch found Asif in the deep.
Afridi (2-21) rounded off an excellent spell by bowling Sean Abbott for a duck, yet another poor Haris ball handed McDermott the chance to clip away the winning boundary.
Captains come up big
Babar gave yet another exhibition of how he has risen to the top of the batting rankings in another sensational knock - his 66 coming at a strike rate of 143.47.
Yet it was World Cup winner Finch who took the trophy, as he showed plenty of patience to stay at the crease for 18 overs, showing why interim head coach Andrew McDonald backed him to stay on as skipper.
Historic tour comes to a close
It has been a brilliant match-up between Pakistan and Australia over the last month or so and the tourists will finally return home.
Australia have now won each of their past four T20Is against Pakistan, the first time they have gone on such a run, though this was the first meeting in the format between the teams in Pakistan.
The tourists reached stumps on day one with a healthy score of 251-3 and inflicted further pain on their opponents by making it to 505-8 by the end of play on Sunday.
Usman Khawaja was responsible for 127 of those runs on day one and looked good value to reach a double hundred after adding another 27 runs unbeaten before lunch.
However, Islamabad-born Khawaja – who has strong family ties to Karachi – was dismissed soon after for 160 from 369 balls by Sajid Khan.
Travis Head was earlier trapped by Sajid for 23 off 48, with a review showing the ball just clipped leg stump, while Nathan Lyon was bowled by Faheem Ashraf for 38.
Australia were 360-6 after losing Khawaja, but Cameron Green (28) and Carey put on 45 before the latter was bowled by Nauman Ali.
Carey looked untroubled alongside Mitchell Starc (28 not out) as he powered towards triple figures, only to be dismissed by Babar Azam on 93 shortly before stumps.
"I guess you want to make those triple figures," Carey said at the end of play. "I think the way the game's going, it was quite an important knock in the end.
"Hopefully tomorrow we see what the skipper does but it's great to have 500 runs on the board."
Decision time for Cummins
After two full days of batting, Australia skipper Pat Cummins must decide whether to declare early on on Monday, as many would expect to be the case.
Pakistan have plenty of work to do if they are to avoid a first defeat to Australia in nine Tests at the National Stadium in Karachi.
Carey keeps Australia in command
Carey was disappointed to miss out on a century, but he still recorded his biggest Test score in what is his seventh outing, his previous highest being 51.
But Khawaja's mammoth 160 – consisting of 15 fours and one six – will be extremely tough to top, the 35-year-old having now notched 257 runs in this series.
Jos Buttler returned to skipper England as captain Eoin Morgan sat out and he top scored with a stunning 59 from 39 deliveries at the top of the order.
Moeen Ali (36) and Liam Livingstone (38) supplied explosive middle-order contributions, but England lost wickets frequently and there was a suspicion their 200 all out in 19.5 was a touch shy of what was required in perfect batting conditions in a sweltering Leeds.
But a Pakistan batting line-up that posted 232-6 in a 31-run win at Trent Bridge on Friday were effectively shackled by leg-spinners Adil Rashid (2-30) and Matt Parkinson (1-25) and Moeen's off-spin (2-32), with paceman Saqib Mahmood the pick of the attack thanks to 3-33 that began with the vital wicket of visiting captain Babar Azam (22).
Jason Roy set the tone for England's innings with a huge six and a four off slow left-armer Imad Wasim (2-37) before holing out within the first over.
Dawid Malan scratched around for one off five deliveries – top-edging a sweep off Imad to be caught by Azam Khan – although there were no such problems for Moeen in his blistering 16-ball stay, nor Livingstone, who followed up his incredible century in Nottingham by bludgeoning two fours and three sixes. One of those remarkably cleared the grandstand at the Football Ground End.
Buttler was in typically sublime touch through extra cover and only fell to Mohammad Hasnain (3-51) with a thunderous hit straight to Babar at mid-off.
Jonny Bairstow, Tom Curran and Chris Jordan came and went without being able to produce anything of similar substance and the sense England had been slightly wasteful was heightened as Babar and Mohammad Rizwan (37) added 50 for the first wicket.
Babar skewed a cross-seam delivery from Mahmood to a diving Malan and, as Rashid and Parkinson got into their work, Pakistan were unable to regain their momentum.
A fine return catch from Rashid accounted for Rizwan, while Moeen had Mohammad Hafeez caught behind for 10 and bowled Fakhar Zaman with a beauty to scoop the player of the match award.
Opener Abid carried his bat through the day to reach stumps on 118 not out and Azhar struck 126, having combined in a mammoth second-wicket stand of 236.
But after toiling on a sluggish surface for most of the day, Zimbabwe and Muzarabani (3-41) made the second new ball pay, as skipper Babar Azam and Fawad Alam followed Azhar back to the pavilion in short order and Pakistan closed on 268-4.
The hosts could at least reflect on having bookended the day effectively.
Pakistan, who handed a debut to veteran seamer Tabish Khan, batted after Babar won the toss, although Imran Butt scratched around for two runs from 20 deliveries before miscuing a pull at Richard Ngarava (1-35).
Given how Ngarava and Muzarabani impressed in their initial burst and what followed, it appears how each team uses the new ball will be vital on a benign Harare pitch.
Although Abid was the more circumspect throughout, the two centurions picked up the pace after lunch as Zimbabwe's discipline began to wane – Azhar enjoying himself backward of square and through midwicket, while Abid showed lovely timing through the covers.
After Zimbabwe persuaded the umpires to change the ball in the 53rd over, slow left-armer Tendai Chisoro (0-80) dropped short and Abid smashed the ball into Roy Kaia's knee, forcing the short leg from the field after lengthy treatment.
Azhar was the first to three figures off 198 balls, while Abid followed from his 224th delivery before a mini-collapse from 248-1.
Muzarabani drew Azhar into a drive on the up, seeing him pouched at gully by Milton Shumba, before Babar edged to Kevin Kasuza in the cordon and Alam dragged on after struggling under a barrage of short deliveries.
Abid and Azhar set up Pakistan for series win
Abid would not have envisaged being joined by Sajid Khan to see out the day, but he will resume alongside the nightwatchman on Saturday having put questions over his place in the side to bed. The opener had a top score of 26 in his 10 Test innings preceding this tour, meaning he needed to back up a 60 in the initial encounter with something more substantial.
There were no such doubts over the 36-year-old Azhar's credentials, but his century was also a redemptive one after being sacked as captain last November.
Babar fed up of counting his Blessings
Azhar's successor Babar has generally become Pakistan's sure thing across all formats and was in blistering form during the recent white-ball trip to South Africa. Not here, though, as he followed up a first-ball duck in his team's innings victory last time out with another single-figure score.
Muzarabani appears to be a big part of the problem. Since returning to international cricket last year, the seamer has removed Babar on six occasions.
The three players along with a non-coaching member of the team management unit will now undergo a period of self-isolation.
All four members are fully vaccinated and without major symptoms.
They will remain isolated from the rest of the West Indies team for 10 days and until they return negative PCR test results under the supervision of Team Physician, Dr. Akshai Mansingh.
CEO of Cricket West Indies, Johnny Grave, explained the positive Covid tests.
“Our arrival testing protocols in Pakistan have confirmed four COVID-19 positives. These were confirmed whilst the players and staff were still in room isolation, so despite this significant setback to our preparation plans, we are confident that the tour can continue as everyone else returned negative PCRs since they have been in Karachi,” said Grave.
Grave said that despite the setback, the team remains in good spirits ahead of the series opener.
“This unusual loss of three players from our squad will seriously impact our team preparations but the rest of the squad is in good spirits and will begin training today ahead of our first game on Monday,” Graves said.
Hurraira was expected to get a chance when the two-match series gets under way in Rawalpindi on Wednesday, having impressed on the domestic stage for Islamabad United.
He scored 218 against a Bangladesh High Performance XI in a four-day match last month, also receiving his first international call-up for a tour of Sri Lanka.
He was not selected for his red-ball debut during that series, however, and he has also been overlooked for this week's first meeting with Bangladesh, despite Imam-ul-Haq being rested.
"We have plenty of riches in our opening batting," Masood said ahead of the Test. "Imam-ul-Haq isn't here for this series.
"We don't limit ourselves to 17 players. We have 20 to 25 players who are part of our squad.
"We initially felt that it was our ideal chance to check Muhammad Hurraira and see what he could offer the Pakistan team after doing so well in domestic cricket in the last three or four years.
"We rested Imam in this series. Saim, who is in good touch now, showed potential in the second innings against Australia.
"As a team, you have to send a message of continuity. So we will try to back the players. We want to give him a fair chance."
Masood also said the expected conditions at the Rawalpindi Cricket Stadium had influenced the decision to select Mohammad Ali to lead the bowling attack.
"You have to look at a few factors," Masood said. "You have to take into account Pakistan's position in the WTC.
"We at least have to win the home matches. Secondly, you have to look at the ground conditions. Thirdly, we have to look at our team combination.
"I think Mohammad Ali gave us the surprise element, we have been seeing it for a long time."
England are in a strong position heading into day five in Multan, after a dominant display of force with both the bat and ball on a record-breaking day on Thursday left Pakistan requiring 115 runs with four wickets remaining, while the tourists also have a second batting innings in hand.
Root, who on Wednesday became England's all-time leading run scorer in Test cricket, put on a partnership of 454 with Harry Brook, who plundered 317.
Former England captain Root was eventually dismissed for 262, his highest individual score, bringing an end to the fourth-highest partnership of any wicket in Test cricket history.
Brook, meanwhile, became the second-fastest player to reach 300 in terms of balls faced, as he became the sixth England player to hit a triple-century and put Brendan McCullum's team on the fourth-highest score in a single Test innings (823-7 declared).
Reflecting on the records while speaking to BBC Test Match Special, Root said: "They are pretty cool things. It would mean a lot more if we can win this Test match. You look at the situation where they had 556 on the scoreboard and to be this ahead in the game is the best thing.
"So many good things have come from it and I am very pleased for Harry. I've never seen an England batter get a 300 and that was nice to watch.
"It's obviously nice and I am sure when I finish my career, I will look back and feel good about it. It will be a nice thing to look back on at the right time. I want to contribute for a long while and make big scores like this one and hopefully win more Test matches for England."
The celebrations from Brook and Root were not huge, and Root put that down to fatigue.
"There was a lack of emotions, partly down to the heat. Just the amount of energy that is taken out of you playing in these conditions is huge. It's been quite pleasing to acclimatise and just drawing that mental resilience," he said.
"I make sure I do the work and put myself in some really tough situations in training so that I am really ready for these conditions.
"I know I can bat for long periods of time and when it gets tough, I can get through it."
The coronavirus pandemic has put the English season on hold until at least July 1, yet the England and Wales Cricket Board is still working on proposals to stage international games on home soil in 2020.
A scheduled Test series with West Indies in June had to be postponed but could still be part of a rearranged fixture list, with action potentially getting under way in early July.
Pakistan could also still visit to play Tests and Twenty20 games, while Roberts declared there is "some chance" Australia will make the trip - so long as there are no health risks - later than originally planned.
England were due to take on their Ashes rivals in a trio of T20 fixtures and a three-match ODI series in July.
"I think there's some chance we could send a team over," Roberts told Sydney's Daily Telegraph.
"Obviously we won't jeopardise the safety of the players, but the best test of that is the West Indian and Pakistan tours of England before we're due to tour. We hope they go off without a hitch."
Wasim Khan, chief executive of the Pakistan Cricket Board, told Sky Sports' Cricket Show that they intend to pick a 25-man squad for a tour that will see fixtures staged at biosecure venues.
"We are trying to get to England early July so that we can get the quarantine done," Khan said.
"If we can practise during that time then great, if not then it gives us just under three weeks to practise.
"We are told there are going to be two venues (to stage matches). We have not been told which the two venues are. We are also told there is going to be a third venue, which is going to be our base while we are in England."
The England and Wales Cricket Board (ECB) has announced skills-based sessions can be carried out at various county grounds while behind closed doors, thereby adhering to distancing guidelines during the coronavirus pandemic.
Bowlers will be the first to return, doing so on a staggered basis with a coach, physio and - where possible - a strength and conditioning coach in attendance.
Both players and staff will have their temperatures checked prior to the training sessions, while dressing rooms and other facilities at the venues being used will be closed.
After a two-week period for the bowlers, batsmen and wicketkeepers will start their individual programmes as the ECB begins working towards playing fixtures during the English season.
"These are the first steps for players return to training ahead of international cricket potentially resuming later this summer," Ashley Giles, managing director of the England team, said.
"The safety of players, staff and our community is our first priority throughout this protocol. We are committed to adhering to public health guidelines and government directives intended to prevent the spread of COVID-19.
"To be clear, we will only train and potentially play cricket behind closed doors if we know it is absolutely safe to do so and is fully supported by the Government.
"We are in constant dialogue with players, coaches and counties to determine what is possible during this period and what facilities will be available to us.
"We are thankful that we have a united front across all of cricket’s stakeholders to prepare the players in a safe and secure environment."
England's Test series with West Indies, originally scheduled for June, was postponed due to the COVID-19 crisis, while Australia, Pakistan and Ireland are still due to visit this year.
The England women's squad is expected to be able to resume training in late June, while the ECB is continuing to work with the 18 first-class counties to "ascertain when a 'back-to- training' protocol can be rolled out" for the domestic game.
Afridi, who still plays Twenty20 cricket at the age of 40, revealed he has been feeling unwell since Thursday.
The all-rounder has since tested positive for COVID-19 and requested prayers for his speed recovery.
He tweeted on Saturday: "I've been feeling unwell since Thursday; my body had been aching badly.
"I've been tested and unfortunately I'm covid positive. Need prayers for a speedy recovery, InshaAllah #COVID19 #pandemic #hopenotout #staysafe #stayhome."
Afridi has been helping with coronavirus relief efforts in his homeland, where 2,551 have died after contracting the virus.
The ECB announced last month that no professional cricket will be played until May 28 due to the spread of COVID-19, though that date could yet be extended.
England are due to face West Indies in a three-match Test series starting on June 4, with a series against Pakistan to follow. Limited-overs games against Australia, Pakistan and Ireland are also on the schedule.
Giles is trying to retain a positive outlook and is open to trying to cram in as many games as possible rather than trimming back the fixture list.
"I'm positive that we'll get some cricket in later in the summer," said Giles. "What exactly that looks like I don't know. But we have to be [positive] when we're planning, otherwise it becomes ever decreasing circles and we just get more and more down on the situation.
"In terms of playing across formats at the same time, we will do whatever we have to do. We will be flexible. By no means would that be ideal but this goes far beyond that. There's some bigger picture stuff here, apart from the health crisis that's going on.
"I don't think anything's off the table, I think it is a blank sheet. If we have to do it, we will. In terms of cricket performance, whilst it not be ideal from a playing point of view, in the long run it might give us a better look at more players and a broader group of people that we might have to play in the future anyway.
"In that sense, it would give greater opportunity. Everything's on the table. I think it would be wrong of me to sit in these meetings – as much as I fight the professional and players' side – there is a bigger picture here and we are going to have to adapt and be as flexible as everyone else."
He added: "In terms of cricket, we're looking at all scenarios and probably with a focus on protecting some of our bigger games. The big games for us in terms of international teams, Test matches, one-dayers, T20Is, looking at scenarios where we can push those back as far as possible without losing any cricket.
"That is possible and I think we have to hang on to hope that we will get out there and we will play. Whether that's behind closed doors or in front of full houses, no one of us quite know. The priority is to doing what the government tells us to do and to keep everyone safe."
Fakhar Zaman, Mohammad Hasnain, Mohammad Rizwan, Shadab Khan and Wahab Riaz are also set to join the team in Worcestershire, the Pakistan Cricket Board (PCB) confirmed on Tuesday.
Pakistan are due to play three Tests and three T20Is in England, but preparations for those matches were plunged into doubt after 10 players tested positive for COVID-19.
However, a PCB statement said: "Fakhar Zaman, Mohammad Hasnain, Mohammad Hafeez, Mohammad Rizwan, Shadab Khan and Wahab Riaz have tested negative for Covid-19 for the second time in three days and, as such, are now eligible to join the Pakistan men's national cricket team in Worcestershire.
"The players were retested on Monday, 29 June, following a first negative test on 26 June.
"The PCB will now start making their travel arrangements and the departure details will be shared in due course."
Kashif Bhatti, Haris Rauf, Haider Ali and Imran Khan tested positive for a second time earlier this week.
The rest of Pakistan's travelling party arrived in Manchester on Sunday and underwent testing prior to a 14-day isolation period in Worcestershire.
On Tuesday the PCB said seven of its team members and a masseur had tested positive, with three others having been found to have the virus on Monday ahead of a scheduled tour to England.
However, on Wednesday Hafeez claimed he did not have coronavirus, tweeting a picture of a test result that showed he was negative.
The all-rounder said he and his family got the all-clear after seeking a second opinion.
England and Pakistan are due to play three Tests and three Twenty20 Internationals from the end of July until September.
The PCB said the latest players to test positive, aside from Hafeez, were Fakhar Zaman, Imran Khan, Kashif Bhatti, Mohammad Hasnain, Mohammad Rizwan and Wahab Riaz, along with masseur Malang Ali.
In a statement, the PCB said its medical panel was "already in contact with these players and the masseur, who have been instructed to observe strict quarantine at their homes for their and their families' wellbeing".
It remains to be seen if Hafeez's latest result will allow him to be free of the same quarantine restrictions.
The Black Caps were scheduled to visit in June and early July, playing a trio of Twenty20 fixtures in Bready before a three-match one-day series at Stormont.
A further two T20 contests were due to take place against Pakistan, listed for July 12 and 14 in Malahide, but those will also not go ahead as originally planned.
The latest update from Cricket Ireland follows on from the cancellation of the three ODIs against Bangladesh in May, though chief executive Warren Deutrom revealed there was no other option in the face of an ongoing global health crisis.
"We deeply regret that we can’t provide any international cricket at home to our fans this year, but we were always up against it with our entire home international programme coming in the first half of the season,” Deutrom said in a statement.
"We want to extend once again our sincere thanks to all those that worked so hard to facilitate what would have been 15 matches across seven venues over three months in Northern Ireland, Republic of Ireland and England.”
New Zealand Cricket chief executive David White remains hopeful the tour can be rearranged for a later date, adding: “I know our players, support staff and Black Caps fans were very much looking forward to the upcoming visit and are disappointed this decision needed to be taken."
Ireland are also set to travel to England for three one-dayers in September. It is possible that series is moved from the original dates, Cricket Ireland confirmed, with discussions still ongoing.
Pakistan are due to start a three-match Test series against Joe Root's side at Lord's on July 30, with three Twenty20 matches also on the itinerary
The coronavirus pandemic has left that schedule in doubt, with England's Test series versus West Indies already having been postponed.
Spectators appear unlikely to be allowed in to venues if and when cricket returns and although Misbah would be disappointed to see the tourists play at empty venues, he thinks international action can help to lift the gloom.
The Pakistan head coach and chief selector told Stats Perform: "It's not ideal obviously, you'd love to go there and perform in an atmosphere with spectators - they are the most important part of any sport.
"It's not ideal, but if you look at it another way, people are mostly locked down in their homes and no sport is going on at the moment.
"They have nothing to watch and mostly COVID-19 news everywhere and people are depressed. In that sort of situation, if we can start sports, if we can start cricket, at least fans can watch that cricket on TV sitting at home and they can enjoy it.
"If you look at in that way, I think if we can do that with proper safety barriers and nobody is in danger, I think we can just go ahead and start from somewhere."
Misbah expects Pakistan players to be ready to hit the ground running when they are able to take to the field again.
He said: "I think in this situation, it's more towards individual responsibility as professionals; what we can do, how we are working.
"We are obviously just trying to communicate to the players that whenever we hit the ground again, the basic thing we need would be fitness. Obviously if we are fit enough, if we maintain our fitness levels, we can regain our form or skill quickly.
"If we lose our fitness in these isolation periods then it's going to be tough because once we are back on the job it will be difficult for us to either work on the skill or fitness. it's important for the players to physically and mentally prepare yourself."
Bangladesh, who visited Pakistan for Test and Twenty20 matches earlier this year, were due to arrive back in the country on March 29 to complete the final leg of their three-part, multi-format tour.
Those plans are now on hold, with the two boards set to discuss options for rescheduling the second Test that was due to begin in Karachi on April 5.
A standalone ODI had also been scheduled to go ahead in Karachi on April 1.
A Pakistan Cricket Board (PCB) statement read: "The Pakistan and Bangladesh cricket boards have decided to postpone the upcoming One-Day International and Test in Karachi for a later date.
"The two boards will now work together to identify a future opportunity to complete the ICC World Test Championship commitment."
Pakistan beat the Tigers by an innings and 44 runs in the first Test in Rawalpindi in February.
The unusual fixture arrangements emerged as a compromise after the Bangladesh Cricket Board expressed concerns over security and player safety in Pakistan.
Meanwhile, the PCB has also indefinitely postponed the domestic one-day Pakistan Cup tournament, which was scheduled to start on March 25.
The Pakistan Cricket Board (PCB) released a statement to reveal the list of names who will be on the chartered flight to Manchester, as well as an update on the situations of those who had previously tested positive for COVID-19.
Of the original 29-man squad, 18 received the all-clear following Thursday's checks, as well as 11 members of the support staff.
They will be joined on the journey by fast bowler Musa Khan and wicketkeeper Rohail Nazir, who have also been tested twice in the past week. Zafar Gohar, meanwhile, will team up with the squad on their arrival in England.The left-arm spinner played a solitary one-dayer for Pakistan in 2015, though he will only be involved in pre-match preparations.
As for those not making the initial trip, they will not be able to travel until returning two successive negative results.
Six players - Fakhar Zaman, Mohammad Hasnain, Mohammad Hafeez, Mohammad Rizwan, Shadab Khan and Wahab Riaz – have done so once and will be tested again next week with a view to joining their team-mates.
Haider Ali, Haris Rauf, Kashif Bhatti and Imran Khan, along with masseur Malang Ali, all tested positive again, however. The PCB medical team has instructed them to remain in quarantine, with their progress to be monitored.
"I want to reassure the players and the official left behind that the PCB will provide them the best support and look after them during the quarantine period," PCB chief executive Wasim Khan said in a statement.
"It needs to be remembered that these players were asymptomatic, which means their chances of regaining complete fitness are higher and brighter than most. As soon as these players test negative twice through the PCB testing process they will be flown to England to join the squad.
"I am aware Mohammad Hafeez and Wahab Riaz took personal tests outside of our process prior to the second PCB testing. While their results came up negative, as per the PCB testing programme, they are deemed to have one negative test following a positive test.
"Therefore, once they are retested and receive a second negative result under the PCB testing programme, they will be available to join the squad in England."
Pakistan are scheduled to play three Tests and a trio of Twenty20 fixtures against England.
Pakistan squad travelling to England: Azhar Ali (captain), Babar Azam, Abid Ali, Asad Shafiq, Faheem Ashraf, Fawad Alam, Iftikhar Ahmad, Imad Wasim, Imam-ul-Haq, Khushdil Shah, Mohammad Abbas, Musa Khan, Naseem Shah, Rohail Nazir, Sarfaraz Ahmed, Shaheen Shah Afridi, Shan Masood, Sohail Khan, Usman Shinwari, Yasir Shah.
England are set to face Pakistan in three Tests and three T20 internationals across July and August but the tour was thrown into doubt over the past week as the initial 29-man touring party was struck by a raft of COVID-19 cases.
Haider Ali, Haris Rauf, Shadab Khan, Fakhar Zaman, Imran Khan, Kashif Bhatti, Mohammad Hafeez, Mohammad Hasnain, Mohammad Rizwan and Wahab Riaz all tested positive.
The ECB said in a statement that players testing positive will not be allowed to travel with the advanced group, with Hafeez's status unclear after the all-rounder tweeted a picture of a negative test and claimed he had received the all-clear.
Test captain Azhar Ali, white-ball counterpart Babar Azam and the remaining players will use Worcestershire's New Road as their training base during their mandatory 14-day isolation period before transferring to Derbyshire's County Ground.
Bilal Asif, Imran Butt, Musa Khan and Mohammad Nawaz have been named as reserves for the Pakistan squad and could make the trip subject to returning negative coronavirus tests.
England's home season has been delayed by the global pandemic but they will host West Indies at the Ageas Bowl next month in the first of three Tests.
