For the December missed test, Coleman was out Christmas shopping at the time when he had said he would be available for sample collection at his Lexington home.

Coleman argued that he returned home inside the 60-minute window, which lasted from 7:15pm to 8:15pm, and that the DCOs must have left early.

The DCOs testified this was not the case, providing a photo taken at 8:21pm, while shopping receipts also cast doubt on Coleman’s claim.

A Walmart receipt showed he had purchased 16 items at 8:22pm.

Coleman claimed he returned home, watched the start of a National Football League game – which kicked off at 8:15pm – and must have then left his home again. 

The Disciplinary Tribunal deemed it was “obvious” that the sprinter in fact did not come home until after that Walmart trip, given other shopping receipts were timestamped at 7:13pm and 7:53pm.

In rendering a two-year ban, the Disciplinary Tribunal described Coleman’s behaviour as “very careless at best and reckless at worst” and viewed there to be no mitigating factors which could have reduced the ban.

The decision could yet be appealed to the Court of Arbitration for Sport.

Coleman previously escaped punishment after missing tests on June 6 2018 and January 16 and April 26 of 2019, successfully arguing that the 2018 case, a filing error, should be pushed back to the first day of the quarter, April 1, and subsequently out of the year-long window.

That allowed him to compete at the 2019 World Championships in Doha, where he won two gold medals.

Coleman won two silver medals at the 2017 World Championships, also in the 100m and 4x100m relay.

He did compete at Rio 2016, but only in the relay heats and was a spectator when the United States were disqualified in the final.
