Britain's Naomi Folkard missed out on a place in the quarter-finals of the individual archery after losing 106-97 to Japan's Nami Hayakawa.
Folkard trailed by two after the first end but a disastrous second end saw her score just 19 out of the 30 points on offer and she was always facing an uphill battle from thereon in, with the result secured before Hayakawa's last arrow.
Peter Cousins was knocked out in the preliminary round of the men's -100kg judo, losing on a golden point to Georgia's Levan Zhorzholiani, while Michelle Rogers was also beaten, losing to Gyeongmi Jeong of Korea.
