Brighton's Ashleigh Ball and the GB hockey women are through to the semi-finals of the Olympics.
A place in the last four was assured when China lost 1-0 to Japan this morning.
GB will finish second at worst in their group and will win it if they beat the Netherlands tonight.
The advantage of victory would be a theoretically easier semi-final against the runners-up of the other group on Wednesday.
A win in the second or third of their remaining three matches will guarantee Ball and GB a medal.
