BOSTON (AP) U.S. runner-up Polina Edmunds has withdrawn from next week's world figure skating championships because of a bone bruise in her right foot.
U.S. Figure Skating announced Wednesday that Mirai Nagasu will take her place.
The injury limits Edmunds' ability to tap with her right foot and perform lutz and flip jumps.
After some tough luck in recent years, Nagasu gets a chance to compete at worlds for the first time since 2010. She was fourth at the Vancouver Olympics as a 16-year-old, then largely struggled for the next several years. She rebounded to finish third at the 2014 U.S. Championships, but was bumped off the Sochi Olympic team for Ashley Wagner.
The 17-year-old Edmunds was eighth at last year's world championships.
