(Reuters) - American Olympic 100 metres hurdles champion Brianna McNeal will miss the Tokyo Games - and even the 2024 Paris Olympics - after the Court of Arbitration for Sport (CAS) dismissed her appeal against a five-year ban for an anti-doping rule violation.

McNeal, who had been charged and provisionally suspended for "tampering within the results management process" in January, was sanctioned by the Athletics Integrity Unit (AIU) as it was her second violation of World Athletics' anti-doping rules.
