Narsingh Yadav,the Indian wrestler’s Olympic campaign hit a huge barricade after the World Anti-Doping Agency (WADA) resoluted to appeal beside the clean chit given to him by NADA in a dope scandal back home.

Rakesh Gupta, the Indian contingent's chef-de-mission informed as,“WADA has appealed against the NADA clearance in Court of Arbitration (CAS). The hearing is on and the IOA Secretary General Rajeev Mehta is there with WADA officials in Rio de Janeiro.”

Narsingh Yadav was supposed to initiate his campaign on August 19 but now faces the vision of a career-ending four-year ban if the Court of Arbitration for Sports (CAS) upholds WADA's appeal.
