Team GB equestrian William Fox-Pitt has dropped out of contention for an individual Olympic medal after suffering a run out during the cross-country event.
The 47-year-old, who is competing at the Games in Rio de Janeiro just 10 months after being placed in an induced coma following a fall, had trouble at Fence 20 onboard Chilli Morning.
Fox-Pitt, who was leading the way in the table, has taken full responsibility for the penalty as he recorded a total score of 67.40.
"I had a very good run, it's just annoying that I went past that third element," Fox-Pitt told reporters. "It was really unfortunate. It was my fault entirely. I went too quickly for him and there was no way I could turn him so he didn't do anything wrong. He is great. He is a lovely horse and to be riding him around the course is a luxury so I'm sad I have wasted it a bit.
"It isn't a pleasurable course to ride but this isn't a pleasurable day, it's a hard work day. Watching those first few horses, you could see it was asking tough questions all the way along and you could see most of them didn't come up with the answers. I hope he jumps well tomorrow.
"We'll be clutching at any chances we have got but we are not going to be in that enviable position of defending a gold medal so we are going to be doing our best and hope the horses feel good."
Fox-Pitt won silver in the team eventing at London 2012.
