China's boxing world champion and London Games silver medal winner found herself at the center of a dispute after a report from Reuters quoted her as saying age fabrication is widespread in Chinese sports.

The report said Ren Cancan's actual birth date is April 26, 1986, making her 26 years old. Officially, however, she is 24 and was born on Jan 26, 1988, the birth date she used to register at international tournaments.

Ren admitted to the fabrication after losing in the flyweight final on Thursday.
