Gabby Adcock battled through a chest infection, but had nothing left to give as her and husband Chris were knocked out of the World Superseries Finals at the semi-final stage.
England’s top mixed doubles pair were comprehensively beaten in the semi-finals 21-9, 21-12 by Olympic champions Nan Zhang and Yunlei Zhao.
“Gabby had nothing more to give,” said coach Pete Jeffrey. “She is really struggling with the chest infection and finding it hard to breathe on court.
“She has performed amazingly well this week despite being ill and I feel that just shows her character and her desire to reach the very top in her sport.”
Despite the defeat, the Adcocks, who won Commonwealth gold in the summer, end the year sixth in the world.
