Lindsey Vonn crashes early in Olympic downhill, taken off the mountain in a helicopter

CORTINA D’AMPEZZO, Italy — Lindsey Vonn, racing on a badly injured left knee, crashed early in the Olympic downhill on Sunday and was taken off the course by a helicopter after the 41-year-old American received medical attention on the snow for long, anguished minutes.

Vonn lost control over the opening traverse after cutting the line too tight and was spun around in the air. She was heard screaming out after the crash as she was surrounded by medical personnel before she was strapped to a gurney and flown away by a helicopter, possibly ending the skier’s storied career. Her condition was not immediately known, with the U.S. Ski Team saying simply she would be evaluated.

The race was put on hold as she received treatment. Vonn’s teammate, Breezy Johnson, held the early lead.

Vonn had family in the stands, including her father, Alan Kildow, who stared down at the ground while his daughter was being treated after just 13 seconds on the course. Others in the crowd, including rapper Snoop Dogg, watched quietly as the star skier was finally taken off the course she knows so well and holds a record 12 World Cup wins.

All eyes had been on Vonn, the feel-good story heading into the Olympics. She had returned to elite ski racing last season after nearly six years, a remarkable decision given her age but she also had a partial titanium knee replacement in her right knee, too. Many wondered how she would fare as she sought a gold medal to join the one she won in the downhill at the 2010 Vancouver Games.

The four-time overall World Cup champion stunned everyone by being a contender almost immediately. She came to the Olympics as the leader in the World Cup downhill standings and was a gold-medal favorite before her crash in Switzerland nine days ago, when she suffered her latest knee injury. In addition to a ruptured ACL, she also had a bone bruise and meniscus damage.

Still, no one counted her out even then. In truth, she has skied through injuries for three decades at the top of the sport. In 2006, ahead of the Turin Olympics, Vonn took a bad fall during downhill training and went to the hospital. She competed less than 48 hours later, racing in all four events she’d planned, with a top result of seventh in the super-G.

“It’s definitely weird,” she said then, “going from the hospital bed to the start gate.”

Cortina has always had many treasured memories for Vonn beyond the record wins. She is called the queen of Cortina, and the Olympia delle Tofana is a course that had always suited Vonn. She tested out the knee twice in downill training runs over the past three days before the awful crash on Sunday in clear, sunny conditions.

“This would be the best comeback I’ve done so far,” Vonn said before the race. “Definitely the most dramatic.”
