QUEENSTOWN, New Zealand - Lindsey Vonn has another injury to worry about after fracturing an ankle bone in a training crash in New Zealand.

"Unfortunately I crashed today and have a small fracture in my ankle," the American skier said on Twitter. "Headed home now but will keep u posted."

She was heading home to Vail, Colorado, to have the ankle examined further. It is the latest setback for Vonn, who returned from serious leg injuries to break the all-time record for victories on the women's World Cup last season. She also won her seventh World Cup downhill title.

Vonn, who was spending a second week in New Zealand for her first on-snow training ahead of the new season, did not say which ankle was damaged. She used the hashtag "minorsetback" in her tweet, indicating she didn't think the injury was very serious.

The World Cup season kicks off with a giant slalom race on Oct. 24 but the first speed events — Vonn's specialty — don't start until a month later.

The 30-year-old Vonn has said she will continue racing through the 2018 Olympics in Pyeongchang, South Korea.
