Adams guaranteed a podium place
Nicola Adams guaranteed Great Britain's first women's boxing medal with victory over Bulgaria's Stoyka Petrova at ExCe, but there was disappointment for Natasha Jonas and Savannah Marshall who both crashed out.
Adams boxed superbly to secure a 16-7 win and book at least a bronze medal, with a place in the Olympic final at stake on Wednesday when she will face irresistible Indian Mary Kom in a guaranteed flyweight thriller.
Jonas produced a proud performance in losing 26-15 to the seemingly unbeatable four-time world champion Katie Taylor from Ireland, in front a crowd whose noise levels were recorded at 113.7 – officially the loudest of the Games so far.
But there was a shocking loss for world champion Marshall, rated as arguably the hosts' best hope of boxing gold, who produced a flat-footed and lethargic performance in going down 16-12 to Marina Volnova of Kazakhstan.
Great Britain's women's hockey team slipped to a 2-1 defeat to Holland, but with their semi-final qualification already secured the only effect was to give them a slightly tougher draw.
Great Britain men's Olympic handball adventure is over after their preliminary stage campaign came to an end, but they saved their best until last in a valiant 41-24 defeat to reigning silver medallists Iceland.
