Sochi, Russia (SportsNetwork.com) - The International Olympic Committee announced on Friday that German biathlete Evi Sachenbacher-Stehle has been excluded from the remainder of the Olympic Games.

Sachenbacher-Stehle tested positive for methylhexaneamine (dimethylpentylamine) after failing an anti-doping test on Monday.

She was also suspended for five days at the start of the 2006 Olympic Winter Games in Turin after test results showed that her blood contained high amounts of haemoglobin.

The 33-year-old Sachenbacher-Stehle spent most of her long career as a cross country skier before switching last season to biathlon. She won gold in 2002 for the 4x5km relay and then gold for the team sprint in 2010.

At Sochi, her best results were fourth place in the women's mass start and also fourth place in the mixed relay.
