But a back injury, which doctors have blamed on the fact she may have suffered a form of tuberculosis as a child -- thus weakening some of the bones in her spinal column -- has put paid to her hopes.

Last week French triple jumper Teddy Tamgho, the European champion and indoor record-holder, confirmed that injury had ended his dream of competing at the Games.
