Here's a look at the latest headlines from the Sochi Winter Games:
-- Under Armour extends speedskating suit deal
Athletic gear maker Under Armour has signed an eight-year deal with with U.S. Speedskating to provide uniforms despite controversy over the suit it provided the team at the Sochi Olympics.
Under Armour spent years developing a new speedskating suit that debuted during the Olympics but flopped. U.S. speedskaters, including favorite Shani Davis, didn't medal, and some blamed the suit. The team reverted to an older Under Armour suit, but results did not improve.
But Under Armour says it is ready to try again. The company will outfit the U.S. speedskating team for the next two Winter Olympics, beginning with South Korea in 2018.
Company CEO and founder Kevin Plank said in an interview with CNBC that Under Armour was "doubling down" and hoped to move past the Sochi controversy.
-- German athlete tests positive
Despite a long list of worries heading into the Sochi Games, the 2014 Winter Olympics have more or less gone off without much of a hitch, but a positive test brought a bit of negativity to the festivities early Friday morning.
An unidentified German athlete failed a drug test the International Olympic Committee announced, marking the first doping case of the Sochi Olympics.
The Germans reported a positive test in the A sample and the IOC is awaiting results of the athlete’s B sample.
If it results in another positive, the IOC will bring official doping chargers.
-- South Koreans support skater, not judges
Kim Yu-Na’s second silver medal of the past two Winter Olympics angered South Korean fans after the gold medal favorite finished just behind Russia’s Adelina Sotnikova, but their vitriol wasn’t directed at the popular figure skater.
According to ESPN.com, Yu-Na’s performance has been repeated over and over again and dissected by Korean television stations who have determined it was a judging error that led to Yu-Na’s somewhat surprising second-place finish.
Many Koreans said Sotniknova benefited from a home ice advantage of one kind or another. South Korea will host the next Winter Olympics in 2018 at Pyeongchang.
-- Americans continue to rack up medals
Team USA widened the medal count gap between it and the rest of the world slightly, pushing its total to 25, including eight gold.
Host Russia has 23 total medals, including seven gold and the Netherland and Canada each have 22.
The Canadians have eight gold after wins in women’s hockey and ski cross while the Dutch have six.
Norway checked in with 21 total medals and the lead in gold, heading to the top of the podium 10 times so far.
-- IOC laughs wolf
Olympic organizers laughed off the prank by a U.S. luger involving a wolf supposedly prowling the athletes' village, and they said Friday that no disciplinary action is being taken.
American talk-show host Jimmy Kimmel said Thursday he cooperated with luger Kate Hansen to post a fake video of a wolf wandering the hall outside the athlete's room in Sochi.
-- Hockey's Chu to carry US flag at closing ceremony
Four-time Olympian Julie Chu will carry the U.S. flag at the closing ceremony of the Sochi Games.
The U.S. Olympic Committee made the announcement Friday, a day after Chu earned a silver medal with the U.S. women's hockey team. It was her fourth Olympic medal -- she has three silvers and a bronze.
Chu says she is "completely humbled and kind of in shock" to be chosen.
A Harvard graduate, Chu has been with Team USA since the 2002 Winter Games in Salt Lake City.
The Americans lost 3-2 in overtime to Canada in the gold medal game Thursday night.
