India lost the T20I series 1-2 after several players of the squad had to be isolated owing to Krunal's infection. Chahal and Gowtham were among his close contacts, who were isolated.
Along with Krunal, Gowtham and Chahal will also have to stay back in Colombo for the time being, reported ESPNCricinfo.
Krunal's brother Hardik Pandya, Manish Pandey, Deepak Chahar and Ishan Kishan will return to the country along with the other members of the Indian contingent. However, England-bound players Prithvi Shaw and Suryakumar Yadav will stay back in Colombo and fly out to the UK soon.
"Yuzi and Gowtham have tested positive as the team was supposed to return by a charter flight to Bengaluru sans Krunal Pandya. But now as per rules, Gowtham and Yuzi will also have to be in seven-day isolation in Sri Lanka," a BCCI source in Colombo told news agency PTI on conditions of anonymity.
The Indian team on Thursday finished the Sri Lanka assignment, which initially was delayed due to multiple COVID-19 cases in the Sri Lankan camp. The ODI series was delayed by five days and then the second T20I had to be deferred by a day after Krunal tested positive for the virus.
