McKayla Maroney will compete with broken toe

A broken toe will not keep McKayla Maroney from performing the enormous Amanar vault which won her the vaulting world championship in 2011. She will compete on vault during Sunday's preliminaries.

Jordyn Wieber, the U.S. all-around champ, and Gabby Douglas, the Olympic trials all-around champ, will each compete on all four events, as will team captain Aly Raisman. Newcomer Kyla Ross will perform on balance beam, uneven bars and floor exercise.

Four women compete in the preliminary rounds, but just the three highest scores will count. The preliminary round qualifies teams for the final day of team competition, as well as the all-around and event finals. Maroney needs to compete on Sunday not just to contribute to the team, but also to qualify for a shot at vaulting gold.

Early reports of an injury seemed like Team USA might be experiencing deja vu. In 2008, Samantha Peszek and Chellsie Memmel were hampered by injury. But Maroney completed her vaults without a problem during Thursday's podium training. Though vault is the only event she'll compete in, it's also her best event and a chance to put up big numbers for the U.S.
