(CNN) She's targeting a historic season but Lindsey Vonn pulled out of a race in St. Moritz after injuring her back Saturday.

The 33-year-old, who is trying to become the most successful ski racer of all time, hurt her back during her run in Saturday's super-G in the glitzy Swiss resort.

She made it to the bottom but slumped to the snow after crossing the finishing line and received lengthy treatment at the course.

Unfortunately I will not be able to race today. I am extremely disappointed but my biggest goal this season is the Olympics and I need to take care of myself now so I can be ready for next week, and more importantly, for February. As always, thank you for the well wishes ❤️🙏🏻

Vonn later tweeted she had an "acute facet (spinal joint) dysfunction. I got compressed on the 6th gate and my back seized up."

Vonn said she would see how she responded to treatment overnight, but she tweeted again Sunday morning ahead of a second super-G: "Unfortunately I will not be able to race today.

"I am extremely disappointed but my biggest goal this season is the Olympics and I need to take care of myself now so I can be ready for next week, and more importantly, for February."

Lindsey Vonn hurt her back in a super-G race in St. Moritz.

Vonn finished 24th in Saturday's race, more than a second behind winner Jasmine Flury of Switzerland, who clinched her first ever World cup podium. Another Swiss Michelle Gisin was 0.1 seconds back, ahead of Liechtenstein's Tina Weirather.

Sunday's super-G was subsequently canceled because of bad weather.

America's Vonn has suffered a catalogue of injuries over her career and began last season's World Cup campaign late after breaking her arm in training last December and then suffering associated nerve problems in her hand.

She began this season by failing to qualify for the second run of a giant slalom race in Solden, Austria, and she crashed in the opening downhill in Lake Louise before finishing 12th in a second downhill at the Canadian resort. She fell again in a subsequent super-G at Lake Louise.

Vonn is bidding to break Swede Ingemar Stenmark's record of 86 World Cup race wins. She trails by nine and is the most decorated women's ski racer. She is also targeting February's Winter Olympics in South Korea after missing the defence of her Olympic downhill title in Sochi in 2014 following knee problems.

Here's a look back at her glittering career. Hide Caption 1 of 18 Photos: Skiing's speed queen She made her Olympic debut at Salt Lake City 2002 as a 17-year-old, finishing 32nd in slalom and sixth in the combined slalom/downhill event. Hide Caption 2 of 18 Photos: Skiing's speed queen Lindsey Kildow -- as she was then before marrying fellow skier Thomas Vonn -- won her first World Cup race with victory in the downhill at Lake Louise, Canada, in 2004. Hide Caption 3 of 18 Photos: Skiing's speed queen In 2005, Vonn signed with Red Bull and began working with a completely new coaching team. She seemed set for the start of something special. Hide Caption 4 of 18 Photos: Skiing's speed queen Any momentum from the new deal was slowed during the 2006 Olympics in Italy, though. A fall in practice resulted in a short stay in hospital. She recovered in time to compete but could only manage seventh in the Super G and eighth in the downhill events.

Hide Caption 7 of 18 Photos: Skiing's speed queen Vonn added a fourth World Cup title in 2012, but is still behind Annemarie Moser-Proell's record of six overall crystal globes.

Hide Caption 9 of 18 Photos: Skiing's speed queen In 2013, Vonn suffered an horrific crash at the World Championships in Austria. She underwent reconstructive knee surgery and began a long road to recovery. She attempted to return a year later, only to pull out of the 2014 Olympics after aggravating the injury again. Hide Caption 10 of 18 Photos: Skiing's speed queen Injuries continued to hamper Vonn. She fractured her left knee in February 2016 in a crash during a World Cup super-G race in Soldeu, Andorra, but raced the combined event the next day before calling an end to her season. Hide Caption 11 of 18 Photos: Skiing's speed queen Vonn worked hard to get back in time to challenge for gold medals at the 2018 Winter Olympics. The American left PyeongChang with a bronze medal in the downhill but insisted she was proud to have made it through her injuries. Hide Caption 12 of 18 Photos: Skiing's speed queen Vonn announced the current ski World Cup season would be her last. She is already the most successful woman in World Cup history with 82 victories and was chasing down Ingemar Stenmark's overall World Cup record of 86 victories in her sights. Hide Caption 13 of 18 Photos: Skiing's speed queen However, a knee injury from a training crash in November meant she couldn't start her season until January. On her debut in Cortina d'Ampezzo, Italy, she was still struggling with knee pain. Hide Caption 14 of 18 Photos: Skiing's speed queen After much soul-searching Vonn announced that she will retire from skiing after competing in the World Championships in Are, Sweden in February 2019. "My body is screaming at me to STOP and it's time for me to listen," she said. Hide Caption 15 of 18 Photos: Skiing's speed queen In her opening race at the World Championships, Vonn suffered a heavy crash and careered into safety netting. She was eventually able to ski to the bottom and said she would still compete in the downhill to bring the curtain down on her glittering career. Hide Caption 16 of 18 Photos: Skiing's speed queen Despite her damaged knees, Vonn was able to retire on a positive note. She battled back to win bronze in the downhill -- becoming the oldest woman to secure a medal at a world championships and the first female racer to medal at six world championships. Hide Caption 17 of 18 Photos: Skiing's speed queen The American retired four wins short of equaling Stenmark's record of 86 World Cup wins and the Swedish great (left) was in Are to watch Vonn's final race. "I basically begged him to come here," Vonn said. Hide Caption 18 of 18

'Represent US'

Earlier this week the two-time Olympic medalist told CNN she would "absolutely not" visit the White House if invited post-Games, but stressed her passion for her country was undiminished.

"Well, I hope to represent the people of the United States, not the president," Vonn told CNN's Alpine Edge.

She added: "I take the Olympics very seriously and what they mean and what they represent, what walking under our flag means in the opening ceremony.

"I want to represent our country well. I don't think that ther are a lot of people currently in our government that do that."

In St. Moritz Friday, Vonn told reporters: "I was asked my opinion and I gave it.

"I mean, it's not necessarily my place to be sticking my nose in politics, but as an athlete I do have a voice."

On the men's World Cup circuit, home favourite Alexis Pinturault won Saturday's giant slalom in Val d'Isere, France, just along the Tarentaise Valley from his native Courchevel.

Pinturault, the Olympic giant slalom bronze medalist, pipped German Stefan Luitz and Austria's Marcel Hirscher.

Hirscher, the six-time World Cup overall winner and slalom world champion, won Sunday's slalom in snowy conditions from Norway's Henrik Kristoffersen and Swede Andre Myhrer in Val d'Isere.
