Two teenagers whose fingers were severed during a tug-of-war game at a California high school were recovering Tuesday, but it was unclear whether doctors were able to reattach the digits. The boy and girl, both under age 18, had stable vital signs after undergoing hours of surgery, Los Angeles County-USC Medical Center spokeswoman Rosa Sacca said. Sacca said she could not release any information on whether surgeons were able to reattach the fingers. They were participating in a lunchtime tug-of-war game on Monday during a Spirit Week celebration at South El Monte High School when they were injured.
