International Gymnast is reporting that two-time Chinese Olympian Cheng Fei has ruptured her Achilles tendon, taking her out of the running for a third Olympics in London.  Cheng Fei was practicing her tumbling during training Thursday morning when the injury occurred.

Now 24 years old, Cheng Fei's Achilles has given her problems since beginning her comeback in 2011.  She had dealt with the pain, and looked to be a contender for the Chinese Olympic team, able to offset the team's weakness on vault and floor.

Cheng is a world-class vaulter, winning World Championship gold on the event from 2005-2007, and becoming the first woman to perform the "Cheng", a half-on, 1 1/2 twisting front off, which now bears her name.  At the Beijing Olympics, Cheng Fei won a gold medal with the Chinese team, as well as bronze medals on vault and beam.

Cheng Fei won vault at the Chinese Nationals earlier this year.
