Greene struggles through hurdles heat
- From the section Athletics
Great Britain's Dai Greene narrowly qualifies for the 400m hurdles semi-finals after finishing fourth in his heat in Moscow.
The defending world champion says his race preparation was "not ideal by any stretch" following an illness at the weekend and tells BBC Sport's Phil Jones he hopes there is "more in the tank tomorrow.".
Greene's time of 49.79 seconds was enough for him to progress as a fastest loser but he was later upgraded to fourth following the disqualification of Puerto Rico's Eric Alejandro.
