Liu out of games

In a stunning development at the track, China's Liu Xiang, the former world
record-holder in the 110-meter hurdles, is done for the Games. Liu was in
the starting blocks for his qualifying heat and after a false start, he
grabbed his right hamstring, and dropped out of the race. He ripped his
lane number off the side of his shorts and immediately left toward a tunnel
beneath the stadium. Liu, a national hero in China, would later be seen on
television receiving medical attention. The crowd at the Bird's Nest was in
shock.
