Distance runner Mo Trafeh banned, results stripped in doping case

Champion distance runner Mo Trafeh banned for four years, results since 2012 stripped in doping case

The doping case against Mo Trafeh has taken a new turn with an arbitrator imposing a four-year ban against the distance runner.

According to the U.S. Anti-Doping Agency, the arbitrator found that Trafeh had used the banned substance EPO on numerous occasions. He has been stripped of all results -- including a record-setting 25-kilometer national championship -- dating back to 2012.

Authorities caught Trafeh with EPO at an airport earlier this year. Though he never failed a test, the USADA built a case against him with witness testimony and other documentary evidence.

"This decision by the independent arbitrator shows the importance of non-analytical case in the effort to protect clean athletes," the anti-doping agency's chief executive, Travis T. Tygart, said.

Born in Morroco, Trafeh became a U.S. citizen in 2008. He has denied any wrongdoing and recently announced his retirement, saying he could not afford the legal costs of contesting his case.

EPO is a synthetic hormone that stimulates red-blood cell production. Its use can improve aerobic performance.
