Drugs rap for USA stars
13 April 2012
Four American athletes have been sanctioned after testing positive for the prohibited stimulant modafinil.
Sprinter Chryste Gaines and hurdlers Sandra Glover, Eric Thomas and Chris Phillips each received a public warning under IAAF rules for a first offence.
Gaines, who competed at the 1996 and 2000 Olympics, and Glover and Thomas tested positive at last year's US championships. Phillips did so during the world championships in Paris.
