Jordyn Wieber replaces Great Britain's
Nicole Hibbert, (placed 22th at
Rotterdam Worlds) who was injured while competing at the English Championships past weekend.
Wieber, a first-year senior, won the junior All-around title at the 2010 Pacific Rim Gymnastics Championships and was the winner of the
2009 Tyson American Cup in Chikago.
On top of the women's field are the 2010 World All-around Champion
Aliya Mustafina of Russia, but on women's side only seven of the 24 Worlds all-around finalists are able to compete in an international top event to such an early time in the season.
Top-class men's roster will lead by
2010 Rotterdam World All-around Silver medallist and winner of the Longines Prize for Elegance
Philipp Boy of Germany and 2010 World All-around Bronze medallist
Jonathan Horton of the United States - in absence of the Japanese World Champion Kohei Uchimura.
