Prithvi Shaw and Suryakumar Yadav's departure from Sri Lanka to join the Indian Test squad in England may be delayed after they were sent into isolation for being in close contact with Krunal Pandya, who has tested positive for Covid-19 in the island nation.
The two were expected to leave immediately after the culmination of the white ball series in Sri Lanka. The series ends after Thursday night's third T20I.
"They will travel to England when the formalities are completed," an official told IANS.
The Indian Test squad in England has already seen three of the players being ruled out. While opener Subman Gill withdrew due to leg injury and has since returned home, off-spin bowling all-rounder Washington Sundar has hurt his finger, and pace bowler Avesh Khan, who was among the standby players, has suffered fracture his left thumb.
As a result, the selectors have pushed Abhimanyu Easwaran into the main squad and have also called up Shaw and Yadav.
The Test series begins on August 4 in Nottingham.
The second Test will be played on August 12-16 at Lord's, London, the third Test on August 25-29 in Leeds, the fourth Test between September 2 and 6 at the Oval, London, and the fifth and final Test in Manchester from September 10 to 14.
The Indian team had lost the World Test Championship final to New Zealand last month.
After a three-week break, the Indian players moved to Durham for a warm-up match and training.
The team will travel to Nottingham on August 1.
