- Lindsey Vonn suffers thumb injury after attempting to break up dogfight
- U.S. star forced to undergo surgery at hospital
- Vonn set to return to competition at Aspen on November 28
- Julia Mancuso ruled out for the season
(CNN)When it comes to thumb injuries, Lindsey Vonn doesn't seem to be having much luck.
The U.S. ski star was forced to undergo hospital treatment on her thumb after attempting to break up a fight between her two dogs, Leo and Bear.
Working her way back to full fitness after breaking her ankle three months ago, Vonn took to Instagram to share the moment with her fans.
On Twitter, she added: "So the story is that my dogs got rowdy fighting over a dang Frisbee and I tried to break it up but got bit instead. Fun weekend."
Leo and Bear are celebrities in their own right and even have their own Instagram page with 13,500 followers.
Vonn is no stranger to thumb injuries. Back in 2009 she sliced it open on a champagne bottle and was forced to race with her right hand taped to the pole at the world championships.
The four-time overall World Cup champion, is set to make her comeback at Aspen on November 28.
Vonn has been dogged by injuries in recent years and was forced to miss the 2014 Sochi Olympics after tearing two ligaments in her right knee.
Her crash in New Zealand back in August was another setback for the most successful World Cup racer who holds the record with 67 victories.
But after having her thumb treated by U.S. ski team physician Dr. Randy Viola, she returned to the slopes where she shot this video.
No go for Mancuso
Vonn isn't the only U.S. skier who has been in the wars.
Four-time Olympic medalist Julia Mancuso will miss the entire season after having hip surgery Wednesday.
Mancuso, who missed the World Cup Finals in March after falling during the giant slalom at Are, Sweden, in December 2014, was troubled by injury last season.
And after missing the season-opener last month, Mancuso has set her sights on making sure she's back to her best by the time the Winter Olympics comes around in 2018.
"If I were to try to push through, get more treatments and try to ski this season, I would just be setting myself back towards the real goal, which is Pyeongchang 2018," she said in a statement.
"My goal is to be strong enough to free ski at the end of March, but conservatively, it depends on the outcome of the surgery."
Mancuso, who won Olympic gold at Turin 2006 in the giant slalom, is expected to return to the snow in March next year.
