Four-time Olympian Julie Chu will carry the US flag at the Closing Ceremony.
The US Olympic Committee made the announcement Friday, a day after Chu earned a silver medal with the 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.
First doping cases
A top German biathlete and an Italian bobsledder were kicked out of the Olympics in the first doping cases of the Winter Games.
Former two-time Olympic gold medalist Evi Sachenbacher-Stehle tested positive for the stimulant methylhexanamine in both her ‘‘A’’ and ‘‘B’’ samples, the German Olympic Committee said.
The committee said she has been removed from the team and was being sent home.
Sachenbacher-Stehle — winner of two golds and three silvers in cross-country skiing at previous Games — blamed the positive test on a nutritional supplement and said she had never knowingly taken performance-enhancing drugs.
The Italian Olympic Committee announced that bobsledder William Frullani tested positive for the banned stimulant dimetylpentylamine in the athletes’ village on Tuesday.
Frullani, who had not competed yet, asked for a backup test that ‘‘confirmed the positive result, resulting in his exclusion from the Italian delegation,’’ CONI said.
French biathlete collapses
French biathlete Marie Laure Brunet collapsed during the women’s relay and was taken to a hospital for medical checkups.
The 25-year-old lost consciousness during the opening leg of the 4 x 6-kilometer relay and was carried off the course.
Team doctor Thomas Lacroix says initial tests were ‘‘reassuring even if she was in a state of hyperventilation. We need to make additional checks tonight and tomorrow.’’
France coach Thierry Dussere says Brunet felt sick and vomited before the race. He says ‘‘this often happens to her before races. She was nervous because she is a very motivated athlete and she wanted to give her best.’’
Brunet hit all five targets in the first shooting and collapsed on her way out of the stadium on the second 2-kilometer lap.
On the prowl
Olympic organizers laughed off the prank by a US luger involving a wolf supposedly prowling the athletes’ village, and they said no disciplinary action is being taken.
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. Instead, Kimmel’s staff rented a wolf and built a set in Los Angeles that was a replica of the dorm and filmed the animal walking around.
‘‘It made me kind of laugh as an individual, not as an IOC spokesman,’’ International Olympic Committee spokesman Mark Adams said Friday. ‘‘I don’t think there’s any harm done. I don’t think it’s anything serious.’’
Sochi organizing committee spokeswoman Alexandra Kosterina said ‘‘we've seen lots of fake photos and fake videos.’’
‘‘It’s their business if they want to do that,’’ Kosterina said. ‘‘It’s OK. People are having fun.’’
Zetterberg has surgery
Red Wings captain Henrik Zetterberg had back surgery and the team expects him to be evaluated again in about eight weeks. Zetterberg played through pain and scored in Sweden’s opening victory over the Czech Republic last week, but that was his only appearance before he left because of a herniated disk . . . Rangers forward Mats Zuccarello will be sidelined because of a fracture he sustained in his left hand while playing for Norway. Zuccarello was evaluated in New York, and diagnosed with a non-displaced fracture — an injury that typically takes 3-4 weeks to heal — the Rangers said . . . German ski cross racer Anna Woerner fractured her right shin and tore a knee ligament during a nasty fall in her quarterfinal heat. The German Olympic Committee says Woerner will need surgery on her knee. Woerner lost her balance on a jump about halfway down the course, her right knee kicking upward. She slammed to the ground and flipped side-over-side before stopping in the middle of the course.
