Montego Bay (Jamaica), July 23 (IANS/CMC): Jamaica's MVP track and field club says it intends to be vigilant in ensuring two of its superstar athletes who tested positive for a banned substance are given a fair hearing.

MVP club says its standing by sprinters Asafa Powell and Sherone Simpson after both tested positive for the same banned stimulant oxilofrine, reports CMC.

"While the Adverse Analytical Findings are unfortunate and disappointing, the club continues to stand by and support Sherone and Asafa during this time," said club president Bruce James, in a statement.
