Skiing great Lindsey Vonn crashes at Crans-Montana, one week before Olympics
The 41-year-old American had skidded out into the safety netting and while she was able to ski down to the bottom of the Swiss piste after her crash, she appeared to be in great discomfort from her left knee.
She was one of several skiers to crash and shortly after her spill, organisers cancelled the race.
Vonn was set to be one of the faces of the upcoming Milan-Cortina Games -- one of seven Americans set to compete at their fifth Olympics.
The race in Crans-Montana -- the site of a deadly fire a month ago that killed 40 young people and injured 116, was set to be the last before the Games start on February 6.
Three of the six skiers who took to the downhill slope in the Swiss resort ended up in the safety nets, after which organisers decided that enough was enough.
"The jury and the organisers have decided to stop the race," they said as Austria's Nina Ortlieb and Marte Monsen of Norway had also careered off piste.
As Vonn was skiing back down to the finish line after her fall, she stopped several times to hold her left knee.
At the bottom of the Crans-Montana piste she seemed to be in tears as she hugged US teammate Jacqueline Wiles.
During her long career, Vonn has torn ligaments in both knees, suffered broken arms and legs, and even a concussion.
Less than two years ago, she underwent a partial knee replacement to resolve persistent pain caused by her multiple injuries.
Just over six months later, she made her comeback to the sport aged 40 following her second retirement in 2019.
Vonn won Olympic downhill gold in Vancouver in 2010, eight years after making her Games debut in Salt Lake City as a fresh-faced teenager.
