Sam Curran has been ruled out of England's plans for the ongoing Test series against India because flying him in for the fourth match would have been too complicated.

It had been intended that Curran would travel to Ahmedabad to be available for what will be England's final Test of the tour, starting on March 4.

But the England and Wales Cricket Board (ECB) said on Thursday that "making secure arrangements for such a journey proved too great a logistical challenge".

Surrey all-rounder Curran played in both of England's Tests against Sri Lanka in January, but he returned home after the series – alongside Jonny Bairstow and Mark Wood – in order to take a break from the team's biosecure bubble.

While Bairstow and Wood have returned to training and are expected to be able to play in the third Test next week, Curran was given extra time off. The 22-year-old, who also represented Chennai Super Kings in the IPL, has spent extended time in team bubbles since July 2020.

England take on India in five Twenty20 internationals and three ODI matches throughout March, and Curran will join members of the limited-overs squad travelling on a charter flight on February 26. He will arrive too late to be considered for the final Test, the ECB indicated.

With no direct flights available from the United Kingdom, Curran would have had to make a stop-over on his way to the Ahmedabad Test. That would have added more risk of contracting the COVID-19 virus, while he would have had to isolate on his arrival in India had any other passenger on his commercial flights returned a positive test.

An ECB spokesman said: "To give Sam the best chance of minimising his risk of exposure to the virus, it was decided to delay his return so that he could travel on the charter flight with the white-ball squad members due to fly on 26 February."

Over 21 Tests with England, Curran has taken 44 wickets for an average of 32.52, while he has 14 limited-overs wickets to his name.

Mohammad Nawaz and debutant Zahid Mahmood starred as Pakistan held their nerve to a seal a 2-1 Twenty20 series win over South Africa despite the best efforts of David Miller and Tabraiz Shamsi.

The Proteas were rocking at 65-7 and thinking of the plane home, with the brilliant Zahid taking 3-40 and Nawaz 2-13 to leave the tourists in a spin in Lahore.

All-rounder Miller made it a contest by clubbing an electric 85 off just 45 deliveries to steer South Africa to 164-8.

Shamsi's outstanding 4-25 made things even more interesting but ultimately the poor showing from the top order told as Pakistan secured a four-wicket win with eight balls to spare.

South Africa started poorly as Mohammad Nawaz's ripper clipped off Reeza Hendrick's (2) thigh and from his next over more early turn saw JJ Smuts (1) sky one that Babar Azam pouched running back from the ring.

Pite van Biljon (16) struck Hasan Ali for three consecutive fours in the sixth over before trying for one too many and seeing the spinner find a huge gap.

Zahid then came to the fore, Heinrich Klaasen (0) top-edging to short fine leg and Janneman Malan trapped lbw, while Andile Phehlukwayo (0) survived a leg before appeal in the same over.

Phehlukwayo fell to Usman Qadir in the next over and Zahid had a third when Dwaine Pretorius (9) - star of the second T20 - had his middle stump torn up.

It was Miller time from there, though, as South Africa's dangerman single-handedly made it a contest - slapping seven sixes and five fours in a sensational knock.

Miller cleared the ropes a couple of times off Zahid in the 13th over, before unloading for four sixes from the final set off Faheem Ashraf to give Pakistan a genuine chase.

Pakistan were looking pretty serene with a 51-run opening stand between Mohammad Rizwan (42) and Haider Ali (15) but Shamsi's turner left the latter's technique exposed and the same man had the former trapped plumb lbw.

Things became even more tense with Shamsi accounting for Hussain Talat (5) and Asif Ali (7), with Babar's industrious 44 coming to an end between those dismissals.

Faheem fell for 10 as Pakistan's legs wobbled but Nawaz (18) and Hasan (20) steered the hosts over the line, the latter clubbing a six over midwicket to seal the series in style.
