The Japan Anti-Doping Agency has ruled that a case involving Kawasaki Frontale striker Kazuki Ganaha did not violate the World Anti-Doping Agency's code, sources familiar with the matter said Saturday. The ruling came after Kawasaki demanded that JADA handle the case, in which the first-division club injected Ganaha with a nutritional supplement in April, saying that the J. League took punitive measures after misinterpreting WADA's anti-doping code.
