Former cross-country champ Smigun denies Turin doping

SOCHI, Russia (Reuters) - Retired Estonian cross-country skier Kristina Smigun-Vaehi, who won two gold medals at the Turin Olympics, denied on Friday taking banned substances after she was told a retest of her sample from the 2006 Games was suspicious.

Smigun-Vaehi, who won two golds in Turin and a silver medal at the Vancouver Games in 2010 before retiring, said she had done nothing wrong.
