Simpson given 18-month drug ban

Jamaican Olympic medallist sprinter Sherone Simpson has been suspended for 18 months after testing positive for a banned stimulant. Simpson, 29, said in January that a supplement provided by her Canadian trainer was responsible for the positive test. But a Jamaican anti-doping panel voted unanimously that Simpson was "negligent in all the circumstances". Olympic discus thrower Allison Randall was suspended for two years.
