Puerta banned for eight years

French Open finalist Mariano Puerta has been banned for eight years for a second doping offence.

The Argentinian, 27, tested positive for the prohibited substance etilefrine following his final appearance at Roland Garros in Paris earlier this year.

It followed a nine-month ban in 2003 after he tested positive for clenbuterol. The new ban is dated from June 5, 2005.
