KRASNAYA POLYANA, Russia (AP) Lindsey Jacobellis' tough luck in the Olympics continues.

The American snowboarder crashed while leading a semifinal race on Sunday, dashing her chances for gold once again.

The 28-year-old Jacobellis was in the lead and well on her way to reaching the finals when she lost her balance coming off a jump at the end of the course at Rosa Khutor Extreme Park. She flailed into a turn before sliding into the snow. She was unhurt but finished last.

Jacobellis, one of the most accomplished snowboardcross riders in the world, famously lost the gold medal in Turin in 2006 when she fell after trying a flashy grab while going over the final jump. She recovered for silver.

Four years ago in Vancouver, Jacobellis crashed during the semifinals and failed to advance.
