Bouchard to sue over New York fall

The Canadian slipped on an unnamed cleaning fluid that had been used on the floor of a physio's room adjacent to the changing area and she then pulled out of the year's final Grand Slam.

She has now launched legal proceedings against both the United States Tennis Association and USTA National Tennis Center.

A lawsuit filed in the US District Court for the Eastern District of New York, in Brooklyn, alleges negligence while it also states the need for a jury trial, with the former Wimbledon finalist seeking substantial damages.

The lawsuit indicates that Bouchard slipped on "a slippery, foreign and dangerous substance" on the tiled floor of the physiotherapy room.
