Christian Coleman of the United States celebrates winning gold in the men’s 100m final at the 17th IAAF World Athletics Championships in Doha in 2019.
Men’s 100m world champion Christian Coleman was banned for two years on Tuesday because of three violations of doping control rules.
Track and field’s Athletics Integrity Unit said Coleman will be banned until May 2022, forcing him to miss the Tokyo Olympics next year.
The 24-year-old American sprinter had been provisionally suspended from competition since May. Weeks later, details of his three missed appointments with sample collections officials in 2019 were revealed.

* World champion runner avoids doping ban after ‘confused’ tester knocked on wrong door
* Athletes risk Olympic dreams by neglecting drug testing requirements
* World’s fastest sprinter Christian Coleman cleared of doping violation
* US sprinter Christian Coleman reportedly missed drug tests, may face suspension
Coleman can appeal his ban at the Court of Arbitration for Sport.
He was favoured to win Olympic titles after taking gold in the individual 100 and 4×100 relay at the 2019 world championships in Doha, Qatar. Coleman was able to run there after a previous whereabouts case against him was dropped.
He got silver in both events at the 2017 worlds in London.
