Hungary's top sprinter Dobos fails drug test

BUDAPEST, Aug 1 (Reuters) Hungary's top 100 metres sprinter Gabor Dobos has tested positive for raised levels of testosterone and faces a life ban, the Hungarian Athletics Association said today.

Dobos failed a test on May 27 in Riga but only received notification this week, federation president Gusztav Rabold told Reuters.

Dobos is awaiting the result of his B sample and if that also proves positive, he will be banned for life because he has already served a two-year suspension after a failing a test in 2000.

Dobos, who leads the Hungarian rankings in the 100m, has been withdrawn from this month's European Championships in Gothenburg together with Hungary's 4x100 relay team, Rabold said.

American Olympic 100m champion Justin Gatlin and Tour de France winner Floyd Landis have both recently tested positive for raised levels of the male sex hormone testosterone, which helps recovery after exercise and increases energy and strength.
