China suffered a huge setback Monday to its hopes of winning gold on the track when superstar Liu Xiang sensationally pulled out of the 110m hurdles, taking the gloss off the hosts’ best Olympics ever.

The country’s 1.3 billion people had been banking on Liu to shine, but he has been troubled by a foot tendon injury and was clearly in pain when he lined up for his race and pulled up before the first hurdle in a false start.

The dejected star, one of the faces of the Beijing Olympics along with basketballer Yao Ming, limped down the tunnel of the Bird’s Nest stadium to a stunned silence from the 91,000 watching fans.

Liu, the defending champion, has been absent from international competition for most of the year and his coach Sun Haiping said the hurdler has been suffering from the Achilles’ heel injury for six to seven years.
