While the ban would have kept Yadav out of the reckoning for Tokyo, the decision to put the Games back to 2021 may have afforded him another Olympic opportunity.
"It is destiny that this opportunity has come my way," Yadav told the Hindustan Times newspaper.
"This is not the time to feel elated because the world and our country are battling a big crisis. But yes, I will be looking to make a return to the mat the moment the ban is over in July."
Yadav had been slated to compete in the 74kg freestyle category at Rio after securing India a berth at the Games by winning bronze at the 2015 world championships.
However, Sushil Kumar, who won bronze in the 66kg category in Beijing in 2008 and silver in London, moved up a weight class and sought a court order for a bout between the two to determine the Rio spot.
The Delhi High Court ruled against Kumar, the only Indian athlete to win two individual Olympic medals, clearing the way for Yadav to compete in Rio.
After two positive tests in June and July 2016, Yadav alleged his supplements and water had been sabotaged and lodged a police complaint against a junior wrestler, accusing him of contaminating his food.
India's anti-doping agency cleared him but WADA filed an urgent application before CAS to challenge the decision.
Yadav, now 31, said he was determined to get on the podium at Tokyo if given the chance to wrestle for India.
"I have not been in touch with the federation but once things get better I will talk to them about my return," he added.
India's wrestling federation said they would not stand in Yadav's way if he wanted to compete for a spot.
"Now that the Tokyo Olympics are postponed for a year, there will be some time before the qualification tournaments start. We will decide once the picture is clear," Vinod Tomar, WFI's assistant secretary, was quoted as saying in the report.
