Former world 100m record holder Asafa Powell has received an 18-month suspension for a positive doping test.
The Jamaican sprinter, 31, took the banned stimulant oxilofrine at last year's national championships but the ban has been backdated from last year so will end on 20 December 2014.
On Tuesday, Jamaican Olympic sprinter Sherone Simpson was also suspended for 18 months for doping.
Both have been banned by the Jamaican anti-doping disciplinary panel.
Simpson, an Olympic 4x100m relay gold and silver medallist, is a training partner of Powell and took the same substance at the same event.
The disciplinary measures are taken from when they first provided a sample - 21 June 2013 - and the pair will now miss the Commonwealth Games in Glasgow in July.
