Double-amputee runner Oscar Pistorius failed to reach the Olympic final of the 400 meters, following a bad start with a slow race and finishing last in his semifinal heat on Sunday night.
The first amputee to compete in track at the Olympics never stood a chance after his slow start and finished the race on his fiber carbon blades in 46.54 seconds, .95 of a second behind winner Kirani James of Grenada.
FULL REPORT: Rock Center with Brian Williams first profiled Pistorius in June.
Pistorius is still expected to run the 4x400 relays, which start Thursday. Last year, Pistorius and South Africa won the silver at the world championships.
