Rio Olympics 2016: Nick Dempsey guaranteed windsurfing silver
Britain's Nick Dempsey is guaranteed silver in the men's Olympic RS:X windsurfing before the final day of competition on Sunday.
Dutch sailor Dorian van Rijsselberghe, who won gold in 2012, will retain his title.
Dempsey, 35, won silver in London, having taken a bronze in Athens in 2004, and will retire after this event.
"Tomorrow's a day off and my birthday, and Sunday is my last ever race so I'm going to want to win," he said.
"I feel very happy to have won a silver medal," Dempsey added. "It's cool, it's amazing.
"It's nice to have had a good spell at the top and be competitive over five Olympic Games. I'm pretty proud of that.
"I'm unemployed as of next week - I'll have to get a job. I'd like to do photography if I can make it work, and a bit of coaching. I'd like some new challenges and new goals and I want to keep being driven in life and achieve something else."
Friday's result is subject to protest and both Dempsey and Van Rijsselberghe will still have to sail in Sunday's medal race.
