The South African blade runner Oscar Pistorius has played down his chances of defending his 100m Paralympic title, assessing that it could be the most open - and fastest - final in Paralympic history.
The 25-year-old, a triple gold medallist in the T44 100m, 200m and 400m in Beijing, made history earlier this month by becoming the first double amputee to compete at the Olympics.
But Pistorius says he'll be happy for a medal of any colour in the 100m this time round, with the final likely to involve world record holder Jonnie Peacock of Britain and world champion Jerome Singleton of the USA.
