Christian Coleman, the 100m world champion, will miss the Tokyo Olympics next year after being banned for two years.
The American runner was banned by the Athletics Integrity Unit (AIU) until May 13, 2022 due to three violations of doping control rules.
Coleman, 24, is not accused of taking a banned substance.
But he missed two visits by sample collectors and failed to provide the correct information on another occasion, all in 2019 – the year he won his world title in Doha.
Events took place on January 16, April 26 and December 9, with the second submission failing that his whereabouts information was not updated shortly after he learned of the itinerary changes.
Coleman was temporarily suspended by the integrity unit in June, and the decision is now upheld by a disciplinary court.
The athlete is ready to appeal against the ban
He claimed that anti-doping officials had not followed through on procedures after he had failed to interview them by the time he said he would return home on December 9.
In court, officers said they were present outside his home in Lexington, Kentucky, during the allotted hour, from 7:15 p.m.
Coleman said he’s back home after the Christmas shopping before the hour-long period expires.
However, receipts showed that Coleman had made a purchase from a supermarket at 8.22 p.m. that evening.
The unit said: “We regret to say that we do not believe that there is any reduction that can be fairly relied upon to reduce the penalty from the two-year period.
“Unfortunately, we see this case involving athlete’s behavior as being extremely careless at best and reckless at worst.”
“We do not accept the athlete’s evidence. It is clear that the athlete did not return to his home until after he bought it at 8.22 pm. We are comfortable because that is what happened,” she added
The athlete complained that doping control officers had not called him that night in December, but the AIU said they were not required to.
In a previous violation, the testers attended and called Coleman outside his home on April 26, 2019.
He told them he was not available for testing because he went to Drake Relays in Iowa.
Four minutes into the call, according to evidence, Coleman updated his whereabouts form to indicate that he was, in fact, in Iowa.
Coleman’s agent Emmanuel Hudson said the ban would be appealed to the Arbitration Sport Court.
The runner won the men’s 100m race at the 2019 World Championships in Qatar Time of 9.76 seconds.
