RIO DE JANEIRO (AP) — Indian wrestler Narsingh Yadav has become the latest athlete to be removed from the Rio Olympics over doping after the Court of Arbitration for Sport gave him a four-year suspension.

Yadav had originally escaped a ban over two positive tests earlier this year for the banned substance methandienone after India's national anti-doping agency accepted his explanation that his food or drink had been tampered with.

However, the World Anti-Doping Agency disagreed and filed an appeal to CAS, which ruled that there was "no evidence" to support Yadav's claim of sabotage.

Yadav had been due to compete Friday in the men's 74-kilogram freestyle class.

Earlier Thursday, weightlifter Izzat Artykov was stripped of his bronze medal after testing positive, while Moldovan canoeist Serghei Tarnovschi is provisionally suspended and risks losing his bronze for a failed test.
