Great Britain's Andrew Pozzi pulled up injured after just two hurdles in his heat this morning.

The 20-year-old had been struggling with a hamstring injury heading into the London Olympic Games.

Having driven out of the blocks, it was clear that the Bristol-based athlete had not fully recovered and he was forced to withdraw at the second barrier.

"The last month has been a nightmare," he told BBC Sport. "I haven't been able to get it sorted. I feel so privileged to be here. I thought I'd give it a go but it just didn't come off."

Cuba's Orlando Ortega won the race in 13.26s, with Hansle Parchment and Konstantin Shabanov trailing in second and third respectively.
