Ankle injury to keep Voisin out of slopestyle skiing

Rosa Khutor, Russia ( - American Maggie Voisin will not participate in Tuesday's slopestyle skiing competition because of an ankle injury.

Voisin hurt her right ankle after falling on a rail feature during a training run on Friday. A silver medalist last month at the X Games, the 15-year-old was considered a medal favorite.

"Maggie distinguished herself as one of the top slopestyle athletes in the world in qualifying for Team USA," said USSA vice president Luke Bodensteiner in a statement Saturday. "We're disappointed for her in being unable to start but have great respect for what she accomplished to get here."

Voisin will not be replaced.

She is the second American to withdraw from competition because of an injury, as Heidi Kloser pulled out of the women's moguls after tearing knee ligaments earlier this week.
