Canadian tennis player Eugenie Bouchard could be in line for a huge compensation pay out after a court ruled the United States Tennis Association (USTA) should take most of the blame for a fall she suffered at the 2015 US Open.

Bouchard, then 21, slipped and fell in the changing rooms after a mixed doubles clash at Flushing Meadows in New York City.

She suffered concussion and had to withdraw from the Grand Slam tournament before her fourth round singles match against eventual runner-up Roberta Vinci of Italy.

A case was launched in a New York court after Bouchard said she fell due to a "slippery, foreign and dangerous substance" on the tiled floor of a physiotherapy room.

The Canadian was number 25 in the world at the time but the incident is claimed to be a "turning point" in her fortunes as she has since tumbled down the rankings.

The now 23-year-old had to miss the rest of the 2015 season and is currently ranked at 121.

It has been ruled by the court that the USTA are 75 per cent responsible for what happened with Bouchard 25 per cent at fault.

This means that the governing body will have to pay three quarters of any compensation sum which is decided upon, with this amount due to be determined following another hearing which begins today.

She could potnetially receive millions in loss of earnings.

Her lawyer, Benedict Morelli, told Press Association Sport: "We are very pleased but not surprised that the jury went in our favour.

"The USTA refused to take responsibility for causing Genie's injury for almost two-and-a-half years."

USTA lawyers reportedly alleged that Bouchard should have known not to enter the changing room area without being accompanied by a trainer or other tournament personnel.

The cleaners who left the substance on the floor were said to have believed all players had left for the night.

Due to her injury, Bouchard also withdrew from the Japan Open, Wuhan Open, China Open and Hong Kong Open in 2015.

The China Open was supposed to be her comeback event in October but she withdrew from the tournament during her first round match with Andrea Petkovic on October 5, after complaining of dizziness.

According to the initial lawsuit, the 2014 Wimbledon runner-up continued to "suffer pain" which resulted in medical costs and a loss of income.

Bouchard and the USTA are yet to comment on the case.
