American sprinter Christian Coleman will miss the Tokyo Olympics after failing in an appeal to overturn his ban for missed doping tests.

Men's 100-meter world champion Christian Coleman was banned for two years on Tuesday, Oct. 27, 2020, for missing three doping control tests. Track and field's Athletics Integrity Unit said Coleman will be banned until May 2022, forcing him to miss the Tokyo Olympics next year. They tracked down receipts from a shopping trip that began, they said, no later than 7:13 p.m., and included stops at Chipotle (at 7:53 p.m.) and Wal-Mart (at 8:22) near Coleman's house. Even with the missed tests, Coleman saw the testers plenty in 2019. Four minutes after the call, according to the evidence, Coleman updated his whereabouts form to indicate he was, in fact, in Iowa.

World champion Coleman and Salwa Eid Naser could miss the Tokyo Games for what are known in the anti-doping world as whereabouts failures. Since early 2001, when the U.S. Anti-Doping Agency's whereabouts system began, there have been 21 whereabouts sanctions out of 175,000 completed tests. Coleman's latest case brought a flurry of Monday morning quarterbacking from the track world, much of it on social media. Set a recurring daily alarm 15 minutes before your hour window. It shows theyre doing their job.The whereabouts system came under a uniform global protocol in 2009.

Christian Coleman, the reigning world champion in the 100-meter dash, was suspended Wednesday by the Athletics Integrity Unit for missing drug tests. He is temporarily banned from competition until a final decision at a hearing conducted under the World Athletics Anti-Doping Rules or the Integrity Code of Conduct. Coleman said earlier on Twitter that drug testers were unable to find him Dec. 9 while he was at a nearby mall Christmas shopping. He said in his post hes been appealing the latest missed test for six months with the AIU, which runs the anti-doping program for World Athletics. 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.___More AP sports: https://apnews.com/apf-sports and https://twitter.com/AP_Sports
