Lindsey Vonn needs thumb stitches after breaking up fight between dogs

Lindsey Vonnwas bitten by the injury bug again. This time, really bitten.

The star American skier needed stitches in her right thumb after trying to break up a fight between her dogs over a Frisbee. On Saturday, she described what happened on her Twitter account and also posted a video of her injured thumb on Instagram.

"This is what I get," Vonn said on her Instagram account.

She also thanked U.S. ski team physician Dr. Randy Viola for fixing her thumb. She's currently healing from a broken left ankle from a crash during training three months ago and recently pronounced herself ready to compete.

Vonn told The Associated Press she plans to ski Sunday and will be fine for a World Cup giant slalom in Aspen, Colorado, at the end of the month.

It's not the first time she's hurt her thumb, either. At the 2009 world championships, she sliced open her thumb on a champagne bottle. Vonn raced with her right hand taped to the pole.

The 31-year-old skier is quite devoted to her two dogs -- Leo and Bear. They even have their own Instagram page, which features pictures of them fishing with Vonn, snuggling with her and even watching sports.

On Twitter, she said: "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."

This has been a rough start to the season for the four-time overall World Cup champion. Her recovery from the broken ankle kept her out of the season-opening giant slalom in Austria last month.

She will also skip a slalom in Levi, Finland, on Nov. 14. But that was the plan all along, as she no longer competes in the slalom.

Vonn captured Olympic gold in the downhill at the 2010 Vancouver Games. She couldn't defend her crown four years later in Sochi because of a serious knee injury.

Her list of injuries over the years is rather lengthy. She withdrew midway through the 2011 world championships because of a concussion. She raced with a severely bruised shin at the 2010 Olympics. She hurt her knee in training and missed a pair of races at the 2007 worlds and took a scary fall during training at the 2006 Olympics, then left the hospital to compete.

Through it all, she's become the all-time winningest female World Cup racer with 67 victories. She surpassed Annemarie Moser-Proell of Austria last season.
