Schwarzenegger's son injured in US ski accident

SUN VALLEY, Idaho: The 18-year-old son of Arnold Schwarzenegger and Maria Shriver says he has been treated for injuries after getting in "a little ski accident" in Idaho.

Patrick Schwarzenegger tweeted Saturday that he received stitches after the accident, and he thanked doctors who he said cared for him in Sun Valley.

He provided a link to a photo he posted to the social networking application Instagram, showing a deep cut on his lower back. He did not provide details on how he got injured.

A request for further details late Saturday from Shriver's spokesman was not immediately returned.

In 2006, Arnold Schwarzenegger broke his leg in a ski accident at Sun Valley while he was governor of California.
