Christian Coleman has been cleared to take part in this month's World Athletics Championships after the United States Anti-Doping Agency (USADA) dropped charges against him on a technicality. 

US sprinter Coleman, the fastest man over 100m this year, had been facing a two-year suspension after drug-testers were unable to locate him on three separate occasions in a 12-month period. However, USADA said in a statement that after receiving guidance from the World Anti-Doping Agency on how the 12-month window should be calculated, it was withdrawing its case.

Coleman is the fastest man in the world over the 100m and the favourite in that distance heading into the 2019 World Championships in Doha, Qatar. He is also expected to run in the 4x100m Relay and the 200m. He has run the two fastest 100m of 2019, a 9.85 and a 9.81 sec.
