RIO DE JANEIRO (AP) — Brazilian sprinter Ana Claudia Lemos, the Brazilian record holder in the 100m and 200m, tested positive for the anabolic steroid oxandrolone, the Brazil Anti-Doping Authority said on Thursday.
In a statement to The Associated Press, the authority only confirmed the case, and said Lemos requested the B sample be tested.
Brazil’s athletics confederation said in another statement that it was still to be informed of the case.
The 27-year-old Lemos is Brazil’s biggest hope for a medal in the 4x100m relay at the Rio Olympics.
Lemos’ coach, Katsuhico Nakaya, could not be contacted by the AP.
