Lindsey Vonn crashed out of the final World Cup downhill before the Milano Cortina Winter Olympics on Friday, leaving the American skiing great limping and clutching her left knee as organizers abandoned the race amid worsening conditions. Vonn has been in outstanding form this season, leading the World Cup downhill standings with five podium finishes from five races, including two victories. Vonn tore the ligaments in her right knee in a high-speed crash at the 2013 world championships and was airlifted from the course. She won Olympic downhill gold at the 2010 Vancouver Games, eight years after making her Olympic debut as a teenager in Salt Lake City. Like her US teammate Mikaela Shiffrin, she is among the most successful female World Cup racers of all time.
