Bajrang staged a remarkable comeback to secure a 4-3 win against USA's Jordan Michael Oliver in the summit showdown of the 65kg freestyle category.
This is the first time that an Indian wrestler has earned an Olympic berth with a medal at the World Championship.
Dope-tainted Narsingh Yadav admitted that his career would be over if the four-year ban imposed on him by the Court of Arbitration for Sports (CAS) is not reviewed and said that the country should take up his case as India lost out on an Olympic medal in wrestling.
Refusing to budge from its stance, the Wrestling Federation of India floated a new theory on Tuesday, alleging that some junior officials of the Sports Authority of India and National Anti Doping Agency are responsible for Narsingh Yadav being handed a four-year ban for doping.
