Great Britain were beaten 11-9 by Russia in the women's water polo tournament, meaning they can now finish seventh at best.
The rematch of a game in the group stages ended in the same way - a narrow defeat for Team GB.
Russia's win puts them in a play-off with China for fifth place in the competition, while Great Britain will play Italy in their final match.
Angie Winstanley-Smith put Great Britain in front in the opening quarter from a man-up situation, before Russia found the back of the net through a long-range effort.
The period ended 3-3, with the home team's scores coming from a Francesca Painter-Snell penalty and a Chloe Wilcox power-play goal. Russia scored from a man-up to take the lead in the second quarter, before Painter-Snell found the back of the net again from long-distance.
Great Britain took a 5-4 lead into half-time after Wilcox was released down the centre and flicked the ball over the goalkeeper.
Russia edged the third quarter by two goals, pushing from a losing position into a winning one.
Goals from Painter-Snell, who bagged her hat-trick, and Hazel Musgrove kept Team GB in the contest as the score was 8-7 to Russia with one quarter remaining. The Russians scored early from a counter-attack to pull two goals clear, before Winstanley-Smith scored a man-up to claw one back.
A penalty put the visitors into double figures, but Wilcox scored a man-up to claim her hat-trick and once again bring Team GB to within one goal of their opponents. However, a long-distance goal for Russia restored their two-goal cushion which put the game beyond the reach of Great Britain.
Ekaterina Prokofyeva scored four for Russia, while Sofia Konukh bagged herself a hat-trick. Evgeniia Khokhriakova netted a brace, as Nadezhda Fedotova and Evgeniya Ivanova scored one each.
