Windsor, Slough, Eton and Hounslow athlete Nigel Levine will not race for GB in the 4x400m relay tonight.

The 23-year-old will be replaced by Dai Greene. Final line-up: Conrad Williams, Jack Green, Dai Greene, Martyn Rooney.

It has been a disappointing end to the Games for Levine, who also missed on the 400m Olympic final when he finished sixth in the second semi-final on Sunday night.
