The Americans need Jordyn Wieber to regain her swagger in a hurry if they're going to hold off Russia for Olympic gold.
The two gymnastic powers have been trading places in team competition for two years and will face off again on the biggest stage for an Olympic title Tuesday night.
The Russians won the world championship in 2010, then finished second to the U.S. last year.
Defending world champ Wieber failed to qualify for the all-around competition at the London Olympics, but the U.S. women will be depending on her for a comeback if they're going to win their first team gold medal since the ''Magnificent Seven'' of the 1996 Atlanta Olympics.
''We're going to have to cheer her up and hype her up,'' teammate Gabby Douglas said.
After failing to qualify for the all-around, the 17-year-old Wieber sobbed and was consoled by teammates. She didn't speak to reporters afterward.
Later, she posted on Twitter: ''I am so proud of our team today and I can't wait for team finals!!''
