Former Olympic champ Liu decides to call time on career
Former Olympic champion hurdler Liu Xiang confirmed his retirement, citing age and injuries 2 and a half years after his last race.
The 31-year-old Liu wrote in a lengthy statement on his microblog titled "My Track, My Hurdle" that he was "truly unwell and old and can no longer run and jump with you."
"Although it's sad, although it's painful, I really have no other choice," Liu wrote.
Liu became the first Chinese man to win Olympic gold in athletics at the 2004 Athens Games in the 110-metre hurdles.
