Liu's injury may require surgery in US

The injury of China's star hurdler Liu Xiang is more severe than expected and Liu may go abroad for surgery, local media reported yesterday.

Liu pulled out of the 110m hurdles first round at the Beijing Olympic Games last month, citing a recurrence of the chronic inflammation in his Achilles' tendon.

As reported by Yangtse Evening Post, Liu may have to undergo surgery in the United States after Sept 20 and said it is hard to decide exactly how long the recovery will take.
