Olympics athletics: Brittney Reese wins long jump gold
American Brittney Reese secured Olympic long jump gold with a leap of 7.12m, but Great Britain's Shara Proctor could only finish ninth.
Proctor, the British record-holder, managed a 6.55m effort - well short of her qualifying jump of 6.83m.
Proctor told BBC Sport: "My first couple of jumps were not good at all and I lost focus and got frustrated."
Russia's Elena Sokolova won silver, while bronze went to Janay Deloach of the United States.
In qualifying for the final, Proctor, 23, was only 12cm short of her own British record, but she could not repeat that form in the final.
The Anguilla-born athlete said: "When I get flustered, I don't perform to the best of my ability. I had a chance (for a medal), I just had to execute and I didn't do that.
"This is my first Olympics and I made it to the finals. That's a big accomplishment for me. I'm not saying I'm satisfied, but I came out here and tried my best. This is a learning experience for me."
