U.S. freestyle skier Maggie Voisin is out of the Olympics because of an ankle injury.
The 15-year-old from Whitefish, Montana, is the youngest member of Team USA. She injured her right ankle during training for ski slopestyle Friday, and doctors deemed she couldn't recover in time for Tuesday's competition.
Voisin was considered a medal contender in Sochi.
She won silver in the X Games and was a discretionary pick by the U.S. Ski Team. The Extreme Park course has come under fire by some riders in the run-up to the Olympics, with American snowboarder Shaun White pulling out of the snowboard slopestyle competition earlier in the week after jamming his wrist.
Luge: Tongan luger Bruno Banani -- formerly known as Fuahea Semi -- shares his name with a German underwear company that paired with the 26-year-old in a unique sponsorship agreement.
When Tongan Princess Salote Mafile'o Pilolevu Tuita set out in 2008 get an athlete from the tiny Polynesian nation into the Winter Games, Banani, then a computer science student and member of the military, beat out dozens of other Tongans and decided to give luge a go. He moved to Germany in 2009 and trained with the sliding power's national team. Needing money to cover the cost of the sport, he approached the company Bruno Banani, which manufactures men's underwear. He changed his name to the company's, and soon the two were partners.
Banani failed to qualify for the Vancouver Games after crashing and suffering a concussion. Though a long shot to medal, he'll be in the field in Sochi and will take his initial runs when competition begins Saturday.
Moguls: American Heidi Kloser had to pull out of the Olympics after injuring her right leg during a training run before moguls qualifying. Kloser tore knee ligaments and broke her femur during a crash Thursday night, only moments before she was supposed to head to the starting gate.
Alpine skiing: Steven Nyman earned the fourth and final U.S. spot for the men's downhill, edging out Erik Fisher and Jared Goldberg with a solid training run Friday. He joins Travis Ganong, Marco Sullivan and Bode Miller.
Ice hockey: Minnesota Wild center Mikko Koivu decided his surgically repaired right ankle has not healed enough to allow him to play for Finland in the Olympics.
Biathlon: Norwegian skiers thought the biathlon track was too short, and they were right. The loop at the Laura Cross-Country Ski and Biathlon Center should measure 2.5 kilometers (1.6 miles), but officials had to add 40 meters (130 feet).
First medals on way: The first five medals at Sochi will be awarded Saturday: the men's 5,000-meter speedskating, where Sven Kramer of the Netherlands opens defense of his lone Olympic title; the men's 10-kilometer sprint in biathlon; the women's moguls; the men's slopestyle final; and the women's 15-kilometer skiathlon, where Marit Bjorgen of Norway, the most successful athlete of the Vancouver Games with three golds, a silver and a bronze, leads a strong Norwegian team.
