Great Britain's medal hopes suffered another blow at the World Athletics Championships as Matthew Hudson-Smith missed out on the men's 400m final.
The British team were set a target of a top-eight finish in the medal table in Tokyo but they remain without a medal four days into the nine-day competition.
Olympic and world silver medallist Hudson-Smith would have held ambitions of a gold medal after missing out on the past two global titles by a combined 0.13 seconds.
But, having complained of a hip issue following his heat on Sunday, the 30-year-old could only manage sixth in his semi-final - with a top-two finish required to guarantee progress.
"There's no excuses. You've got to do what you've got to do," Hudson-Smith told BBC Sport.
"It's a race, I executed to the best of my ability, and that's all that matters. I'm going to take some time out and re-evaluate."
Charlie Dobson, the second-fastest British 400m runner in history after Hudson-Smith, and team-mate Sam Reardon also missed out.
It comes after 2024 world indoor pole vault champion Molly Caudery suffered an injury while warming up before her qualification event, while Emile Cairess - fourth at last year's Paris Olympics - could not complete the men's marathon.
Elsewhere, 2023 world bronze medallist Zharnel Hughes and world indoor 60m champion Jeremiah Azu were unable to reach the men's 100m final.
