Great Britain's Bianca Walkden suffered a last-gasp defeat to South Korea's Lee Da-bin in the Olympic taekwondo +67kg semi-final.
The 29-year-old could still repeat the bronze she won in Rio four years ago and will fight again at 13:00 BST.
Walkden had a two-point lead with three seconds left on the clock, but Lee landed a head kick with one second remaining to win 25-24.
Team GB's Mahama Cho lost his opening bout in the men's 80kg category.
