Former 100 metres world record holder Asafa Powell has been banned from athletics for 18 months for doping.
The 31-year-old Jamaican sprinter has competed at the last three Olympics and broke the world record in 2007 when he ran the 100 metres in 9.74 seconds at an event in Italy.
Powell tested positive for a banned substance in July of last year.
