During a prolonged hearing spanning more than three hours, Narsingh's lawyers pleaded that the 26-year-old was a victim of circumstances and urged the panel not to put a ban on his Rio Olympic prospects.

Narsingh's chances of participating in the upcoming Rio Games came under a cloud last Sunday when he returned a positive result for a dope test conducted by the NADA on June 25.

Following this, the Mumbai-based grappler, who was selected to represent the country in the men's 74kg freestyle category ahead of two-time Olympic medallist Sushil Kumar, was handed a provisional suspension.

He ran into further trouble on Wednesday after it was announced that a second test conducted on July 5 has also returned a positive result.

Meanwhile, under pressure from the United World Wrestling, a hesitant Wrestling Federation of India (WFI) on Tuesday, named Parveen Rana for the replacement slot in order to preserve India's Olympic quota in the 74kg freestyle category.

WFI President Brij Bhushan Sharan Singh said that Rana's name was sent on July 25 -- which was the last date for naming replacements -- to secure the Olympic quota.

"Although Praveen Rana has been named as replacement for Yadav if he gets a clean cheat, I am ready to fight another battle for him to secure his Olympic berth," Singh told IANS.

"Rana's name was sent to secure country's Olympic quota and the proposal was accepted on July 26. If we wouldn't have recommended Rana's name, we would have missed our quota," he added.

Singh, however, is still hopeful that Narsingh has a slim chance of participating in the quadrennial extravaganza, something which looks a distant possibility going by Sports Minister Vijay Goel's comments.

"His road to the Olympics has not completely ended. Now, it's up to Yadav to prove his innocence. Once given clean cheat, he will go for the Olympics," Singh said.

The minister on Wednesday said that no player in the Olympics squad can be substituted if he or she has been suspended by an anti-doping panel.

"I don't think any person is allowed as replacement of another, if the original player has failed the dope test," Goel told reporters in Parliament.

"In case a player is seriously unwell, then under extraordinary circumstances the concerned agency considers substituting another player," the Bharatiya Janata Party (BJP) leader added.

But Singh refuted Goel's claims, saying, "The minister is unaware of the rules. He is saying such things due to lack of information. Rana's name has already been accepted”.
