Chris and Gabby Adcock have been forced to withdraw from their World Championship quarter-final in Indonesia.
The English duo, who are husband and wife, had been hoping to reach the last four of the event for the first time in their careers.
However, after Chris was deemed too ill to play, the pair were unable to take part in their clash with Liu Cheng and Bao Yixin.
The duo won gold in the mixed doubles at last year's Commonwealth Games in Glasgow.
