Memmel suffers ankle injury while training
Chellsie Memmel hurt her right ankle while training on the floor exercise Sunday in Beijing.
“USA Gymnastics is monitoring Chellsie on a daily basis,” USA Gymnastics president Steve Penny said in a statement on the organization's website.
Associated Press added this from Memmel: "We're taking things a day at a time, but I was able to do good bars today."
Alternates Ivana Hong, Jana Bieger and Corrie Lothrop are training in Tokyo and could fly to Beijing should Memmel not recover in time.
Memmel, the 2005 world champion, has suffered a series of injuries, including a broken foot that caused her to miss the 2004 Olympics in Athens.
