Ireland's Thomas Barr has been forced to withdraw from the World Championships in London after being struck down by gastroenteritis.
The Ferrybank athlete, who came fourth in last year's Olympic Games in Rio, was due to run in tonight's 400 metres hurdles semi-finals at the London Stadium after squeezing through the heats yesterday.
The bitterly disappointed Waterford man told RTE Sport: "I'm gutted to have to withdraw from today's semi final. I wasn't feeling great yesterday evening and later in the night I was hit with a bad bout of gastroenteritis.
"My whole year has been focused on the World Championships. The support yesterday was just brilliant and to not be able to go out and compete today for Ireland is beyond disappointing."
Barr's absence means that there will be no Irish involvement at the championships today.
Question: how would you react to a doping question if you're a clean athlete? Would you view it as an affront, a wolf of an accusation dressed up as a sheepish question, and go on the offensive against whoever had the audacity to ask it?
