COLORADO SPRINGS (Colorado) (AFP) David Clinger, runner-up in last years US national road race championships, has been slapped with a two-year ban after testing positive for performance-enhancing drugs. The 32-year-old American tested positive for synthetic testosterone and modafinil in July at the 2009 national championships in Bend, Oregon, the US Anti-Doping Agency announced on Friday. Synthetic testosterone is prohibited as an anabolic agent and modafinil is prohibited as a stimulant on the World Anti-Doping Agency Prohibited List, USADA said in a news release. This is the latest setback for Clinger, who is a former US Postal teammate of Lance Armstrong and Floyd Landis. He has been in and out of drug rehab facilities. He is also known for an unusual New Zealand Maori-inspired tattoo which covers his entire face like a mask. USADA said the suspension is retroactive to the date Clinger was first notified of the ban by US officials meaning he will be eligible to compete again in 19 months. His has also been stripped of his race results. Clinger told the discipline panel that he was taking the drugs on the advice of his personal doctor in Utah and that he declared the use of testosterone on the forms that accompanied his test sample. The disciplinary panel rejected USADAs request for a longer suspension than two years.
