Husband and wife pair Chris and Gabby Adcock have had their mixed doubles world title bid ended by illness.
They were aiming to reach the last four for the first time at the event in Jakarta but Chris was too ill to play.
"Devastated," he said on Twitter, after withdrawing from their quarter-final with Liu Cheng and Bao Yixin.
In the men's doubles, Marcus Ellis and Chris Langridge went down 21-16 22-20 to Indonesia's Mohammad Ahsan and Hendra Setiawan.
In the men's singles, top seed and defending champion Chen Long survived a mammoth second game to advance to the semi-finals with a 21-18 30-29 victory over Danish seventh seed Viktor Axelson.
Spaniard Carolina Marin advanced to the last four of the women's singles as she beat China's Wang Shixian 21-17 21-19.
