Jack Whelbourne's hopes of claiming a medal at the Winter Olympics disappeared when he crashed out in the 1500 metres short track final in Sochi.
The 22-year-old from Nottingham, who had qualified from his semi-final in second spot with a thrilling performance, fell with three laps to go holding his right foot.
Canada's Charles Hamelin, who had won Whelbourne's semi-final, went on to take gold, the third of his career on the ice.
Han Tianyu of China took silver while Viktor Ahn earned the bronze, giving Russia its first-ever short track medal. He had struck gold in the event back in 2006, though then he was racing for South Korea.
Whelbourne, who will be assessed ahead of the men's 1000m on Thursday, said: "Unfortunately a block got under my foot and I toed in, which has given me a twisted ankle.
"It can be quite common in the sport. The block move, we have seven and up to eight people racing with tight-knit overtakes, so it happens quite a lot and this time it happened to me, unfortunately when I was in my best form. I am really pleased with my performance."
No serious damage
The British Olympic Association released a statement on Monday evening, saying tests had revealed there was no serious damage to Whelbourne's ankle.
"Following the final of the men's short track speed skating 1,500m, Team GB athlete Jack Whelbourne was taken for a precautionary X-ray of his right ankle," it read.
"The X-ray revealed no fracture and Whelbourne will now be monitored further in the coming days, when a decision will be made as to his ability to compete in further events."
Meanwhile, Elise Christie and Charlotte Gilmartin successfully made it through their opening heat in the women's 500m event. They will both now be back in action on Thursday for the quarter-finals.
"Me and Elise both had lane four which isn't the best lane but we both got the job done," Gilmartin - who finished second in her race - said.
"This being my first Olympics, I probably came here thinking this was a kind of a build-up to the next one so I didn't put much expectation on myself, I wanted to give my best performance and see what happens."
