World and Olympic 100 metres champion Justin Gatlin has been banned for a maximum of eight years by the United States Anti-Doping Agency after admitting he committed "a doping violation".
The 24-year-old American was facing the prospect of a life ban after testing positive for testosterone at the Kansas Relays in Lawrence on April 22.
Gatlin first failed a drugs test five years ago when amphetamines were found in his samples at the USA Junior Championships.
Although the IAAF later accepted he was using the medication to treat Attention Deficit Disorder, it was still registered as a first offence and under the two-strikes rule, Gatlin faced being thrown out of the sport for good.
* An American athlete has been banned after failing a drug test taken at Birmingham's NIA earlier this year.
John Capel, a former world 200 metres gold medallist, has accepted committing a doping violation under International Association of Athletics Federations' rules when cannabis was found in his sample at the Norwich Union Grand Prix on February 18. The 27-year-old has been banned for two years from March 15, it being considered a second offence following a public warning in 2004.
That occurred just before the Olympic Games and saw him withdrawn from the 4x400m relay, when he produced a positive test for marijuana at a team match between the USA, France and Germany in Munich.
