Katarina Johnson-Thompson’s medal hopes in the Olympic women’s heptathlon were effectively ended as she pulled up injured in the 200m.
The British world champion came into Tokyo 2020 with injury worries after a serious Achilles problem and had barely competed this year.
Going into the 200m, the 28-year-old had slipped two places to fifth after finishing 15th in the shot put.
She got up to finish the race but was then disqualified for leaving her lane.
Johnson-Thompson started quickly but pulled up as she rounded the bend and went into the straight.
The Liverpudlian, who had heavy strapping on her right Achilles, covered her face with her hands as she writhed in pain on the track.
After refusing to be taken off the track in a wheelchair, she picked herself up to jog over the line.
It is the latest blow for Britain’s athletics team after sprinters Adam Gemili and Dina Asher-Smith both suffered with injuries.
Whether Johnson-Thompson will be fit enough to compete in Thursday’s final three events remains to be seen.
BBC trackside reporter Jeanette Kwayke said Johnson-Thompson did not want to speak to the media as she left the track.
“I think we all thought it was amazing to see her run in the hurdles but there was limping after the high jump and there was always going to be a lot of stress on the Achilles,” Beijing 2008 Olympian Kwayke added.
