Banned coach Alberto Salazar appeals to CAS

Alberto Salazar has appealed to the Court of Arbitration for Sport against the four-year ban handed down by the United States Anti-Doping Agency (USADA).

The 61-year-old American, who coached British four-time Olympic champion Sir Mo Farah between 2011 and 2017, was punished for breaching doping regulations but has sought to challenge that decision.
