Jamaican anti-doping authorities have found positive back-up doping tests for sprinter Asafa Powell and four other local athletes.
The Jamaican Anti-Doping Commission (JADCO) will now hand over to the country's anti-doping disciplinary panel to discuss when hearings for the athletes - which also includes Powell's team-mate Sherone Simpson - will take place.
It is another blow for the Jamaican athletics community which is already facing the prospect of doping punishment for triple-Olympic gold medallist Veronica Campbell-Brown.
Campbell-Brown was suspended in June after she tested positive to a banned diuretic at a meet one month prior.
Although her case looks to involve unintentional use of a banned substance, the scandals have hit the incredibly athletics-proud country hard.
Renee Anne Shirley, formerly with JADCO, recently said the group did not have enough man-power to carry out the stringent testing required to regularly catch people using banned substances.
She also said only one out-of-competition test was done between February of last year and the beginning of the 2012 Olympics in London.
