US ski star Lindsey Vonn broke an ankle while training Thursday in New Zealand, she said.

"Unfortunately I crashed today and have a small fracture in my ankle. Headed home now but will keep u posted," the 30-year-old American said on Twitter. She gave no other details.

Vonn, on her second week of training in New Zealand ahead of the new season, only returned from serious leg injuries to set a women's World Cup win record last season.

The American star is a goodwill ambassador the 2018 Pyeongchang Winter Olympics and has said she will keep competing until the Games.
