The Court of Arbitration for Sport has cleared Japanese Olympic silver medallist Koki Ikeda of anti-doping violations, overturning a four-year ban and making him immediately eligible to compete. In a separate case, the Athletics Integrity Unit handed Ethiopian marathon runner Ruti Aga a six-year ban for using a prohibited steroid and attempting to cover it up.
