World 100 metres champion Christian Coleman of the United States said on Tuesday that he is facing a possible suspension after another violation of the anti-doping whereabouts rules.
Coleman, in a lengthy statement on Twitter, said that he is facing a ban from the Athletics Integrity Unit (AIU) after missing a test on Dec. 9.
Three failures to properly file whereabouts information in a 12-month period can result in a one or two-year suspension.
Coleman had looked in danger of missing last year’s worlds in Doha when the U.S. Anti-Doping Agency (USADA) filed - and later withdrew - a whereabouts violation charge.
“I want to make you all aware of a situation I’m currently dealing with,” said Coleman in a statement posted on Twitter. “A few days ago, the AIU came to a decision that I’ve been appealing for six months that I missed a test on December 9th, 2019.
“And now this might result in me being suspended from other filing failures that occurred well over a year ago at this point.”
