World 100m champion Christian Coleman will miss next year’s Tokyo Olympics after a two-year ban.
Doping was banned until May 13, 2022 by the American Sprinter Athletics Ingredients Unit (AIU) for three violations of doping control regulations.
Coleman, 24, is not charged with possession of a prohibited substance.
However he missed two visits by sample collection officials and he failed to file accurate information on another occasion, all 2019 – the year he won his world title in Doha.
The incidents took place on January 16, April 26 and December 9, with a filing failure related to him not updating his location information after learning of his travel change.
Coleman was temporarily suspended by the AIU in June and the decision is now upheld by a disciplinary tribunal.
He claimed that anti-doping officials did not follow the procedure after failing to meet with them on 9 December.
Officers at the tribunal said they were present outside his home in Lexington, Kentucky, from 1:15 p.m. at the time of the assignment.
Coleman said he returned to the country after Christmas shopping an hour before the end of the slot.
Receipts, however, showed that Coleman made a purchase from a supermarket at 8.22pm.
The AIU said: “We are sad to say that we do not think that a fairly reliable measure can be taken to reduce the amount of approval from a two-year period.
“Unfortunately, we see this case as as reckless and most reckless as being involved in the behavior of an athlete.”
It added: “We do not accept the athlete’s evidence. Apparently the athlete did not return home until his purchase at 8.22 pm. We are comfortable with the fact that it happened.”
The athlete complained that doping control officers did not call him that night in December but the AIU said they did not need him.
In a previous breach, investigators called Coleman on April 26, 2019, from in front of his home.
He told them he was not available for testing because he went to Drake Relay in Iowa.
Four minutes after the call, according to evidence, Coleman updated his location form to indicate that he was actually in Iowa.
Coleman’s agent, Emanuel Hudson, said the ban would be appealed to the Sports for Arbitration Court.
The sprinter won the men’s 100m at the 2014 World Championships Qatar With a time of 9.76 seconds.
