Athletics: Medallists not among drug cheats

Re-testing on 400 urine samples taken during the Paris championships is not yet complete but with about 75 percent of the results now in, “a very small number” had tested positive for tetrahydrogestrinone, or THG, according to IAAF spokesman Nick Davies.
