Hopes of medal iced; WINTER OLYMPICS.
Whelbourne led early on in the short track final and was lying second as the race pace hotted up but, with three laps remaining, the 22-year-old from Nottingham lost his footing and fell to the ice, ending his medal dream and hurting his ankle in the process.
Whelbourne will be hoping the ankle recovers in time for him to take part in the men's 1000m on Thursday.
In the women's short track, British hopefuls Elise Christie and Charlotte Gilmartin both came through their respective 500m heats with few problems to qualify for tomorrow's quarter-finals.
Britain's men made a winning start to their round-robin curling campaign as they saw off hosts Russia 7-4 but were then beaten 8-4 by Sweden.
The women lost a difficult round-robin opener against reigning Olympic champions Sweden 6-4.
