The Jamaican Football Federation has confirmed that a player tested positive for a banned substance after a World Cup qualifier last month.
The unnamed player failed a doping test following the 2-0 defeat to Honduras in Tegucigalpa on June 11, a result that effectively ended Jamaica's chances of qualifying for the World Cup finals in Brazil next year.
The news is another blow to sport in the country after Jamaican sprinters Asafa Powell and Sherone Simpson tested positive for the banned stimulant oxilofrine last month.
A JFF statement read: "During the World Cup qualifying match, Honduras vs Jamaica, on June 11, 2013 a member of the Jamaican squad returned an adverse analytical finding on his urine sample.
"The player has been informed and we await further information from FIFA.
"The JFF has taken this matter very seriously and a thorough investigation has already started by the chairman of the JFF Medical Committee."
