BEIJING, Sept. 3 -- 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.

China's Liu Xiang kneels down while warming up prior to the first round competition of men's 110m hurdles at the National Stadium, also known as the Bird's Nest, during Beijing 2008 Olympic Games in Beijing, China, Aug. 18, 2008. The defending champion Liu Xiang dropped out after getting injury.

After the conclusion of the Beijing Games, Liu and his coach Sun Haiping returned to his hometown of Shanghai last Friday.

Having a one-day rest at home, Liu returned to his training base in Shanghai for upper body training and healing of the injury.

Currently, the 25-year-old is undergoing examination by domestic experts and he will not seek for further treatment in the US unless his injury is in stable condition.

A doctor, who conducted the initial examination, told the Shanghai Evening Post that it will take about one year for Liu to get fully fit.

"My foot is not as swollen but I still cannot run," Liu was quoted by Liberation Daily of Shanghai. "When I tried to exert strength I could feel great pain. After the swelling goes down the doctors will work out a plan to perform a radical cure. I will continue training my upper body and remain optimistic."
