Britain qualified for the Olympic field hockey semi-finals for the first time since it won the 1988 Seoul Games by surviving a dramatic finish to 1-1 draw with Spain on Tuesday.
Britain will face the Netherlands in the semi-finals.
Spain, the Beijing Games silver medallist, thought it could steal a victory in the last two minutes when it had two penalty-corners saved, a third canceled on video review, and another penalty-corner request rejected on a referral.
Britain's Ashley Jackson scored the first goal, his team-leading fifth, by drag-flicking a penalty-corner into the bottom right corner in the 37th minute.
Spain leveled with 16 minutes to go through a penalty-corner from Pau Quemada, who blasted into the lower left corner.
