The Winter Olympics Opening Ceremony is Friday, along with mixed doubles curling, figure skating and training for Alpine skiing, luge and ski jumping.

The 41-year-old making a comeback on a partially rebuilt knee just tore a ligament in her other knee. But experts say her hopes of competing anyway aren’t totally outlandish.

Lindsey Vonn needed to use a crutch to get around over the weekend. Now she’s performing box jumps, working out in a pool while wearing a weighted vest, and skiing at high speed.

Lindsey Vonn finally has an opportunity to test out her injured knee on the Olympic slopes during a downhill skiing training session in Cortina.

The American Alpine star, 41, who suffered the injury in a crash last week, says, “I have not deviated from my plan.”

Lindsey Vonn inspected the Olympic downhill course with other racers early Friday as she prepared to take part in the opening training session despite tearing the ACL in her left knee a week ago. The 41-year-old Vonn is planning to compete at the Milan Cortina Games with a large brace covering her injured knee.

Lindsey Vonn wiped out in a downhill race on Jan. 30. She got up limping, then was airlifted from the course. The diagnosis: a ruptured ACL — a season-ending injury for most.

U.S. ski star Lindsey Vonn refused to give up on her Milan Cortina dreams even after suffering a devastating knee injury. She resumed training just days after an ACL injury.
