Britain's Paula Radcliffe's Olympic hopes have evaporated after she withdrew from the London 2012 marathon because of injury.
Speculation had been rife the 38-year-old world record-holder would pull out after a foot problem flared up again and today the news was confirmed.
A statement on the UK Athletics website read: "The British Olympic Association and UK Athletics announced this afternoon that marathon athlete Paula Radcliffe is being withdrawn from Team GB due to medical reasons."
It added: "Radcliffe has been suffering with a foot problem and after a fitness test on Sunday it was concluded that she would not be able to race competitively to the best of her abilities."
