Brazil's Olympic sprint hopeful Vanda Gomes faces a two-year ban after a positive doping test.
The 26-year-old was found to have traces of aromatase-inhibiting drug anastrozole in a urine sample in September, reports Xinhua.
She has been temporarily banned by the Brazil's athletics federation (CBA) pending a ruling from the country's superior sports justice tribunal. A date for the hearing is yet to be set.
Gomes was a member of Brazil's gold medal-winning 4x100m relay team at the Pan American Games in Guadalajara in 2011.
Anastrozole, commonly prescribed to breast cancer sufferers, works by inhibiting the synthesis of estrogen.
