Hansle Parchment's bronze was Jamaica's first medal in the men's high hurdles.

In the final heat, 2004 gold medalist Liu Xiang reminded viewers of his 2008 performance, failing to clear the first hurdle, and injuring his right achilles.

Refusing a wheelchair assist and medical attention, he returned to the track and hopped all the way to the final hurdle.

Returning to his assigned lane 4, Liu kissed the top of the tenth hurdle, perhaps signifying the end of his Olympic career.

He then hopped across the finish line, where he was assisted off the track by heat winner Andy Turner, Balázs Baji and Jackson Quiñónez.

Merritt continued to a personal best 12.92 and a .12 win over reigning world champion Jason Richardson.

Parchment took another .02 off his national record for the bronze, the rest of the field was not even close, more than a quarter of a second behind.

The 2004 gold medalist Liu Xiang of China, who had been unable to run in the first round in 2008 due to injury, also returned.

The men's 110 metres hurdles competition consisted of heats (Round 1), semifinals, and a final.
