American world 100 metres champion Christian Coleman has appealed against his ban for breaching anti-doping whereabouts rules at the Court of Arbitration for Sport (CAS). CAS, sports' highest court, said it had registered Coleman's appeal after he was banned for two years by the Athletics Integrity Unit's (AIU) disciplinary tribunal last month and is set to miss next year's Tokyo Olympics.
CAS said Coleman in his appeal "requests that the decision of the AIU’s disciplinary tribunal be set aside and that the sanction be eliminated, or in the alternative, reduced,"
Under the so-called whereabouts rule, elite athletes must make themselves available for random out-of-competition testing and state a location and one-hour window where they can be found on any given day.
Three failures to properly file whereabouts information or being absent during the hour stated in a 12-month period can result in a one or two-year suspension.
