LONDON (AP) — The IAAF says the doping case involving Jamaican sprint star Veronica Campbell-Brown appears to involve a "lesser" offense.
The three-time Olympic gold medalist was suspended by Jamaica's national federation on Tuesday pending an investigation into a positive drug test.
Jamaican officials said Campbell-Brown tested positive for a banned diuretic at a meet in May.
IAAF spokesman Nick Davies tells The Associated Press "all evidence seems to point to this offense being a lesser one," meaning possible unintentional use of a banned substance.
Under global anti-doping rules, some diuretics are classified as a "specified substance," a designation for drugs that might have been consumed without intent to enhance performance.
Athletes can receive a reduced sanction if they can prove how a substance was ingested.
