World 100m champion Christian Coleman has been banned for two years after missing three drugs tests.
The 24-year-old American, who is suspended from May 14, 2020, will miss the postponed Tokyo Olympics next summer. Coleman won 100m gold at the World Championships in Doha in 2019.
The indoor 60m world record holder has 30 days to file an appeal to the Court of Arbitration for Sport (Cas).
He was provisionally suspended in June after missing a third test in December 2019.
Three whereabouts failures in a 12-month period can result in a ban of up to two years.
Coleman did not contest his first missed test on January 6, 2019, but disputed his filing failure on April 26, 2019, and whereabouts failure on December 9.
The investigation into his rule violations said there was no suggestion he had ever taken a prohibited substance.
According to the Athletics Integrity Unit’s (AIU) out-of-competition testing guidelines, athletes are accountable for missed tests if they are not at their specified location for the one-hour period they have stated. The tester must wait for the full 60 minutes before leaving.
Coleman said he was Christmas shopping “five minutes away” from home, and that the tester made no effort to contact him during his third whereabouts failure.
He also said on social media that he would be “willing to take a drug test every single day for the rest of my career” to prove his innocence.
Doping control officers said they waited outside for a full hour, ringing and knocking every 10 minutes.
The AIU said shopping receipts belonging to Coleman suggested he was “obviously” not at his home for the entirety of the one-hour period.
The US Anti-Doping Agency (Usada) initially charged Coleman with missing three drugs tests in 12 months, before his world 100m victory in September 2019.
It withdrew the case after it was proved there had been a filing irregularity regarding the date of the first missed test. (BBC Sport)
