Dutt wrote in a tweet that he had been promoted to silver but there hasn’t been any official confirmation yet.

The Indian lost his last-16 encounter with Kudukhov, but after the Russian reached the final, Yogeshwar got another chance in the repechage round and went on to beat North Korea’s Ri Jong-myong for bronze.

The United States’ Coleman Scott, who lost to eventual champion Toghrul Asgarov of Azerbaijan in the semi-finals, will now be the sole bronze medallist.

He would be upgraded in the event that Asgarov was disqualified. 

Kudukhov, a four-time world champion and 55kg bronze medallist at the Beijing 2008 Olympics, died in a car crash in southern Russia in December 2013.

He was killed when a heavy-duty vehicle collided with his vehicle on the federal highway near Armavir as he was travelling from the city of Krasnodar.

Another wrestler to reportedly test positive is Uzbekistan’s Artur Taymazov, a three-time Olympic champion in the men’s 120kg freestyle category, according to the Indian Express.

His samples were collected during Beijing 2008, where he won the second of his three gold medals.

If confirmed, Russia’s Bakhtiyar Akhmedov will seemingly get upgraded to gold on the back of this with Slovakia’s David Musuľbes, who lost against Taymazov in the semi-finals, moving up to silver and Kazakhstan’s Marid Mutalimov being the sole bronze medallist.

"The samples of five wrestlers, including Russia’s Besik Kudukhov and Uzbekistan’s Artur Taymazov’s, have tested positive for banned substances," United World Wrestling (UWW) told the Indian Express.

"Kudukhov failed a dope test in re-tests of samples collected during the London Games."

The Wrestling Federation of India (WFI) says it has been informed about the decision but is waiting for a written confirmation from the International Olympic Committee before making an official statement.

"Hearing into his case had been on in the CAS [Court of Arbitration for Sport] for a while but a decision has come only now," a WFI official told the Hindustan Times.

"We are still waiting for a written communiqué." 

An IOC spokesman has told insidethegames that the names of those wrestlers who have tested positive will be announced "as they are analysed and dealt with, not in one single consignment".

Dutt was eliminated by Mongolia’s Ganzorigiin Mandakhnaran in the round of 32 at Rio 2016, where fellow Indian wrestler Narsingh Yadav was initially cleared of a doping offence before being banned for four years by the CAS.

If Dutt’s upgrade is confirmed, he will become the second wrestler from India, after Sushil Kumar, to win silver at an Olympics.

Kumar was second at London 2012 in the men’s 66kg freestyle.

insidethegames has contacted UWW for comment and is currently awaiting a response.
