Wrestler Sandeep Tulsi Yadav has failed a dope test which was held on Sunday. He tested positive for steroid during the test.
Sandeep received a bronze medal at 2013 World Championship in the 66 kg category.
Earlier, Narsingh Yadav was also tested positive for a banned steroid. He will not able to play in the match.
Wrestling Federation of India (WFI) said it strengthens the conspiracy theory and indicates at a clear case of sabotage.
"The fact that Narisingh's roommate at the camp has also tested positive for the same substance, it clearly looks to be a foul play. Both the wrestlers were consuming the same supplements as they were roommates. It arises suspicion," WFI assistant secretary Vinod Tomar said.
"There was a high quantity of steroid in the sample, which is hard to believe. It seems like a deliberate thing. Why would anyone take such high dose?"
“Only these two guys have failed it and this clearly indicates that something is wrong,” WFI said.
NADA Director General Navin Agarwal said, Narsingh Yadav got 'B' sample tested positive for a banned substance.
Sources said that he had returned positive for methandienone – a banned anabolic steroid.
"This is a conspiracy against me. I have never taken any banned substance," said Narsingh.
