Indian wrestler Narsingh Yadav, who competes in the 74kg freestyle category, has tested positive for COVID-19.
Along with Narsingh, 77kg Greco Roman grappler Gurpreet Singh and India wrestling team physiotherapist Vishal Rai have also contracted the coronavirus.
"All three are asymptomatic and have been moved to Sonepat's Bhagwan Mahavir Das Hospital as a precautionary measure," the Sports Authority of India (SAI) revealed.
The positive results came to fore after the three rejoined the national wrestling camp at SAI's Sonepat centre after a brief Diwali break.
As per the SAI Standard Operating Procedures, the COVID-19 tests were conducted on all personnel on the sixth day - Friday, 26 November - of their return.
The 31-year-old Narsingh Yadav was all set to participate in his first international tournament in four years after serving a doping ban.
Narsingh was named for the Individual World Cup in Belgrade which will be held from December 12 after fellow Indian wrestler Jitender Kumar pulled out owing to an injury.
With the COVID-19 pandemic, Narsingh has had no opportunities to test himself on the international arena this year with all events being cancelled or postponed. Gurpreet Singh, meanwhile, managed to win a gold medal in the Rome ranking series tournament in January.
In September, three grapplers – Deepak Punia (86kg), Navin (65kg) and Krishan (125kg) - tested positive for the virus after reporting for the national camp.
The women’s national wrestling camp, meanwhile, was postponed last week after most grapplers opted to continue training at their homes due to the ongoing pandemic.
