Niall Treacy was well behind the field in his 500m heat when he skidded out of the race
Team GB's Niall Treacy suffered his third crash in as many short track speed skating events as his Winter Olympics ended when he failed to progress from the 500m heats.
The only British representative in short track, Treacy surprisingly reached the 1500m final on Saturday but crashed out and then also fell in the 1,000m heats.
The 25-year-old says the shortest distance is his least favourite, declaring himself to be "not a natural sprinter".
Treacy had a wobbly start as he was clipped on the opening corner by South Korea's Rim Jong-un - an 18-year-old high school student who won bronze in the 1,000m - to require a restart.
