Brazilian officials say five athletes tested positive
Brazilian officials say five athletes preparing for the upcoming world championships in Germany have failed doping tests.
The Brazilian athletics confederation said Bruno Lins Tenorio de Barros, Jorge Celio da Rocha Sena, Josiane da Silva Tito, Luciana Franca and Lucimara Silvestre presented \"adverse results\" in out-of-competition tests conducted by the confederation on June 15.
The athletes, who were already in Germany for this month\'s competition, requested their B samples be tested and are returning to Brazil to present their defense.
Three of the five athletes were at the Beijing Olympics last year Barros helped Brazil finish fourth in the 4 by 100-metre relay, Silvestre competed in the women\'s heptathlon and Tito was in the women\'s 4 by 400 relay.
