England's Chris and Gabby Adcock failed in their bid to make the final of the World Superseries Finals in Dubai.
The Commonwealth Games gold medallists were beaten 21-9 21-12 by world number ones Zhang Nan and Zhao Yunlei.
The Chinese pairing despatched the Adcocks in the semi-final in just 36 minutes, with Gabby Adcock playing despite suffering from a chest infection.
The English husband-and-wife pair finish 2014 ranked sixth in the world.
"Gabby had nothing more to give today. She is really struggling with the chest infection and finding it hard to breathe on court," said Pete Jeffrey, Badminton England's national coach.
"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."
