Oscar Pistorius' history-making participation at the world championships ended with a silver medal after his teammates guided South Africa to second in the 4x400m relay on Friday.
The controversial 'Blade Runner', who runs with carbon fibre prosthetic running blades and was the first amputee to compete at the worlds, finished last in his semi-final heat in the individual 400m.
He was omitted from the relay team for the final, having run the first leg in qualifiers on Thursday, when South Africa finished third quickest.
"Haven't been included in the final for the SA men's 4x400m. Pretty Guttered," Pistorius tweeted. As a relay squad member, however, he will be returning home with a world silver in his pocket after his teammates battled off Jamaica for second behind a strong US quartet.
