Injured Chinese hurdler Liu Xiang waits before a surgery on his torn right Achilles tendon at the Wellington Hospital in Britain on August 9, 2012. Liu received the surgery on Thursday afternoon (London time). The 29-year-old Liu exited the London Games after smashing into the first obstacle of his 110m hurdles heat on Tuesday, four years after he was forced to withdraw due to a tendon injury from his heat at the 2008 Beijing Games.
