Goel also made it clear that Narsingh's dope case will be dealt as per international rules with the strict implementation of the WADA Code.
In his introductory remark before a press conference, Goel said India will be represented by 119 sportspersons (from earlier 120) in Rio Olympics.
"NADA is an autonomous body established under the WADA Code to promote clean sports and check doping. In Narsingh's case, we will ensure that WADA Code is implemented. We are committed to the WADA Code," he said while announcing the 'Run for Olympics' programme to be held here on July 31.
"Both of Narsingh's A and B dope samples have returned positive. He has been placed under provisional suspension and so we now have 119 athletes. That's why I said India will be represented by 119 athletes," the minister said when asked if Narshing still has a chance to take the Rio bus.

"The NADA has disciplinary panels to deal with doping cases. He (Narshing) will get a fair chance to defend himself and present his case before these panels. There will be justice under the rules and beyond that there is nothing much we can do in this case," said the minister who took charge this month.
On whether the government will agree to a probe on the issue as demanded by Narsingh, Goel evaded the question.
"Law will take its own course and we cannot do anything. Let the NADA panels deal with the case and then we will see," he said.
India's Olympic buildup was dealt a huge blow yesterday as Narsingh, who was selected ahead of the celebrated Sushil Kumar, failed a dope test.

Top Sports Authority of India officials were furious that Narsingh has talked about a conspiracy to frame him after both his samples returned positive for anabolic steroid. They said that Narsingh's case is an open and shut case.
"He is in the dock now and he should first prove (that he is innocent) himself and then say all these things like he has been framed and there was a conspiracy," the official said.
"Every athlete who has tested positive in the past has claimed that they are innocent and they are being framed. It is not new. We will see what the NADA disciplinary panel decide," added the official.
"Likewise, there is also no chance for Sushil Kumar to represent India in Rio. It is over, the deadline for sending entries is over. India will not be represented by any wrestler in the 74kg freestyle."
Asked if there could be any swapping of dope samples, the official said, "I don't think this can happen. If he thinks it can happen, and if he writes to us officially alleging that it could happen, we have to do a DNA test and we are not saying that we will do it or not. But he has to first tell us that officially."
"He (Narsingh) has not informed or written anything (against any SAI official) earlier when he thought there was something happening. But he is making a complaint just now, after the dope case.
