Team GB's Jade Jones has qualified for the women's -57kg taekwondo final.
Jones produced a superb display to beat South Korea's number one seed Tseng Li-Cheng 10-6 to guarantee at least a silver medal.
The 19-year-old lost the opening round 2-0, but after halving the deficit in the second, she stunned Tseng with a head-shot to lead 5-2 late in the third round.
The South Korean coach argued that Tseng had scored a three-point shot with 15 seconds remaining but the appeal was dismissed and Jones roared back to win 10-6 to progress to tonight's final.
