Only grapplers who directly secure quota places themselves will be eligible for consideration.

There will be no trials between rivals for specific places unless they have each secured quota spots.

This differs from the system used to select Indian teams for other events including World Championships and both Asian and Commonwealth Games.

It comes after a legal row between Narsingh Yadav and Sushil Kumar for the sole under-74 kilograms freestyle spot on the team at Rio 2016.

Yadav, a gold medallist at the 2010 Commonwealth Games, secured a quota spot by virtue of his bronze medal winning performance at the 2015 World Championships.

He was therefore selected over two-time Olympic medallist Kumar, who had missed that event.

Kumar unsuccessfully appealed to the Delhi High Court to overturn the verdict and force a trial.

In the end, though, neither participated in Rio after Yadav was removed from the team after failing a drugs test. 

It is hoped that announcing the system for Tokyo 2020 now with three years still go will help improve clarity and reduce confusion.

“It’s final," WFI secretary general Vinod Tomar told the Hindustan Times, 

"There will be no change in the selection policy for the Olympic Games.

“Since the grapplers are aware of the strategy of the WFI, we hope there won’t be any controversy this time around.”

Sakshi Malik secured India's only wrestling medal at the Rio Olympics with bronze in the women's under 58kg freestyle division.
