Sydney: The Australian Olympic Committee said Friday it has asked Wrestling Australia to withdraw the nomination of Vinod Kumar for the Rio de Janeiro Games over a doping violation.

The AOC said Kumar tested positive in April at the African/Oceania Olympic qualifier in Algeria where he won a silver medal, and both his A and B samples were positive. It did not name the drug.

The AOC said Kumar had been suspended for four years but had 30 days to appeal to the Court of Arbitration for Sport.

It also said the international federation, United World Wrestling, had advised they will reallocate his position in the 66-kilogram Greco-Roman weight division to an athlete from another country.

The AOC's website said the India-born Kumar, 31, became an Australian citizen in 2015.
