Eugenie Bouchard Sues United States Tennis Association Over Fall On 'Slippery' Floor

NEW YORK — Tennis pro Eugenie Bouchard has filed a lawsuit against the United States Tennis Association after she slipped and fell in a locker room during the U.S. Open.

In a lawsuit filed Wednesday in U.S. District Court in Brooklyn, Bouchard claims her fall was caused by a "slippery, foreign and dangerous substance" on the floor.

Bouchard says she suffered a severe head injury, which caused her to withdraw from the tournament. She also dropped out of a tournament in China.

Her suit claims the USTA, tennis' national governing body, was negligent. It seeks unspecified damages.

Bouchard says her world ranking has dropped 13 spots since the incident and she believes it is likely to continue to drop.

USTA spokesman Chris Widmaier says the organization does not comment on on-going litigation.
