Liu Xiang crashes out of London 2012 after falling at the first hurdle of 110m hurdles heat

Xiang hopped in agony down the length of the track on his left leg. He took a rest, leaning heavily on one of the hurdles, and then, roared on by 80,000 in the Olympic Stadium who felt like crying for him, one of the world’s great athletes stoically carried on his way to the finish line where his competitors gathered to console and help him into a wheelchair.
