The crowd at Olympic Stadium went silent when British hurdler Jack Green fell early in Saturday night's semifinals.

Green was in tears after failing to advance to the 400-meter hurdle finals.

"I hit hurdle three because I'm an idiot," says Green, who bloodied his knees.

It was a humbling moment for the young sprinter, who is now hopeful he'll still be considered for Britain's relay team.

"I'm not good enough on this level like I thought I was," he says. "I need to get on that relay team and show people what I can really do with a baton in my hand."
