Great Britain's wheelchair curlers crashed to their heaviest ever Winter Paralympic defeat as they were humbled 13-4 defeat by Finland in Sochi on Tuesday.

A day after celebrating a 12-2 thumping of previously unbeaten Slovakia, their biggest Games victory, Aileen Neilson's rink were outclassed, losing a four and a five-stone end.

Skip Neilson was even replaced by Angie Malone after the fourth end with her team 8-1 down, but the change could not spark a comeback.

At one point Britain trailed 13-1 and looked in danger of slipping to the heaviest loss in Winter Paralympic history. It was still Britain's worst defeat, though, eclipsing their 9-2 reverse to Germany in Vancouver four years ago.

It signalled a dramatic return to earth against the side ranked 13th in the world, especially after fifth-ranked Britain had beaten the world's numbers two and three, Sweden and South Korea, before their success over Slovakia.

The loss left Britain with three wins and two losses from their five games at the Ice Cube Curling Centre so far, with Norway up next in their second game of the day.

Up in the mountains, Britain's skiers were made to wait for the chance of more medal success as the super combined event was delayed by thick fog at the Rosa Khutor Alpine Centre.

Organisers announced the super-G part of the event, which had been set to take place on Tuesday morning, would be run on another, as yet undecided, day, with the second part, the slalom, due to get under way first at 2pm local time (10am GMT) on Tuesday afternoon.

Kelly Gallagher and guide Charlotte Evans, who on Monday won Great Britain's first ever Winter Paralympic title, and team-mates Jade Etherington and guide Caroline Powell were due to go in the visually impaired super combined.

Sit skiers Anna Turney and Mick Brennan were set to compete also.
