BEIJING -- The International Olympic Committee asked the international gymnastics federation Friday to reexamine whether gold-medal-winning gymnast He Kexin and two of her teammates were too young to compete in the Beijing Games.
"You shouldn't regard this as a formal investigation, but we have asked the international gymnastics federation to look into a number of questions and discrepancies on these cases," IOC spokeswoman Giselle Davies said.
