Top Indian javelin thrower Shivpal Singh’s ban period was on Tuesday reduced from four years to one as the Appeal Panel of the National Anti-Doping Agency (NADA) accepted his contention that “contaminated supplement” was behind his flunked dope test, his lawyer said. 

The Anti-Doping Disciplinary Panel of NADA on August 16 last year had sanctioned Shivpal, who participated in the Tokyo Olympics, for four years after his dope sample tested positive for a steroid in an out-of-competition test in September, 2021.
