World 100 metres champion Christian Coleman has filed an appeal against his ban from competition until May 2022 for breaching anti-doping 'whereabouts' rules.

The 24-year-old Coleman was handed the sanction last month after being found guilty of two missed tests and one 'finding failure' in 2019.

According to the Court of Arbitration for Sport, Coleman's appeal "requests that the decision of the AIU (Athletics Integrity Unit) Disciplinary Tribunal of 22 October 2020 be set aside and that the sanction be eliminated, or in the alternative, reduced".

Coleman, who won individual and relay gold at Doha 2019, has not been accused of taking a banned substance.
