Silva fails doping test after winning judo gold

RIO DE JANEIRO -- Olympic judo champion Rafaela Silva of Brazil failed a doping test at the recent Pan American Games in Lima, Peru, she said Friday.

The 27-year-old Silva said she tested positive for fenoterol, a drug used to treat asthma.

The judoka insisted she was innocent and blamed the positive test on having had frequent contact with a 7-month-old baby who suffers from asthma.

Silva became the first Brazilian to win gold at her home Olympics in Rio de Janeiro in 2016. She also won the Pan American title in the same 57-kilogram category in August.

Silva's attorney Bichara Neto said the judoka will not be suspended or lose her Pan American Games title before organizers hear her defense.

The Brazilian is one of the favorites to win gold at the Tokyo Olympics next year.
