Yogeshwar, who travelled all the way to Las Vegas with the Indian contingent following speculations around his fitness, has been advised to withdraw from the men's 65kg freestyle category after doctors at the venue did not find him 100 per cent fit.
Asked why Yogeshwar was sent to the USA when he was not 100 per cent fit, a top WFI official said that the 32-year-old had assured the federation that he was in good shape and would be able to participate in the tournament.
The WFI now doesn't wish to risk aggravating his injury.
"He does not have a major injury, just a niggling one but as a precaution, he has been advised against participating in the World Championship. He should not aggravate his injury. And since there are four more qualification tournaments left before the Olympics, it is not wise to take risk," said the official.
He has been asked to take complete rest and also undergo another knee operation.
