US sprint star Christian Coleman denied on Saturday a statement to NBC accusations of breaches of its obligations anti-doping locations and was confident in the decisions that will be taken on September 4 after a hearing with investigators.

"The supposed and widely circulated information that I have not fulfilled my obligations is simply wrong, and I think that at the hearing on the 4th of September we will be able to close this story and I will be able to participate in the world championships in Doha this autumn. "said Christian Coleman to Ato Boldon, a consultant for NBC Sports and himself a former 100-meter star.

"I'm not the type to take supplements, whoever they are, I'm not worried about anti-doping tests at any time," he added.

"After the hearing I will be able to express myself on the subject, but for the moment I have to reserve my comments and respect the process".

The fastest sprinter of the year on 100 meters (9 sec 81), Christian Coleman (23 years) would have missed three times its location obligations in one year, announced several media Thursday.

This would constitute an anti-doping offense, but the American would seek to challenge one of these absences to avoid a suspension, according to several media including the UK's Daily Mail newspaper website, which revealed the information citing "close sources" .

According to the current anti-doping rules, athletes must indicate their geographical locations to the anti-doping authorities 90 days in advance.

If he fails to justify these alleged failures, Coleman, vice-world champion in the 100m in 2017 behind compatriot Justin Gatlin but before the legend Usain Bolt, risk a two-year suspension, reduced to a year at best. It could also miss the Tokyo Olympics in 2020.
