Thomas Barr, one of Ireland's greatest hopes for a medal at the 2017 World Athletics Championships in London, has pulled out of the games due to gastroenteritis.
The Waterford man, who came fourth in the final of the 400m hurdles at the Rio Olympics last year, was due to run in tonight's in tonight's semi-final in the British capital.
He told RTÉ:
"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."
