Christian Coleman, the 24-year-old American world 100m champion, has been provisionally suspended by the Athletics Integrity Unit (AIU) after missing a third doping test on December 9, 2019.
According to the AIU, Coleman's third whereabouts failure has been confirmed, which could result in a ban of up to two years.
Coleman has disputed the third whereabouts failure, claiming he was Christmas shopping just five minutes away from home and the tester made no effort to contact him.
"I have never and will never use performance-enhancing supplements or drugs," Coleman posted on social media.
He added, "I am willing to take a drug test every single day for the rest of my career for all I care to prove my innocence. I have nothing to hide but it's not possible to show that if I'm not even given a chance to."
Coleman had previously missed a test on January 16, 2019, and experienced a filing failure on April 26, 2019.
His chances of competing in Doha last August had looked slim after the US Anti-Doping Agency charged Coleman with missing three drugs tests in 12 months, but the case was later withdrawn due to a filing irregularity.
