Eugenie Bouchard is already suing the WTA for her fall at the U.S. Open; she might as well sue the governing body for the way it calculates points for rankings.

Both could end up costing her money.

Eugenie Bouchard Lawsuit vs. WTA Could Be Fear-Based

Bouchard dropped to No. 48 in the world rankings as she continues to take time off from a concussion she suffered slipping on a locker room floor at the U.S. Open in September, according to Yahoo Sports Canada.

She "slipped" in the rankings because of a quirk in the WTA rankings that reflects "the fact that the WTA Tour erases all the points earned at its two year-end final tournaments before they begin, unlike the usual procedure of having each week's events drop off the rolling 52-week ranking system once the tournaments are completed," Yahoo Sports reported.

"That's how Bouchard rose, briefly, to her career-best No. 5 a year ago; the quirk in the calculations benefits players who didn't qualify for the Tour Finals the previous year as those who did play lose any points earned."

Bouchard now will enter the 2016 Australian Open unseeded, meaning she could be forced to face a top-ranked opponent in the first round. The top 32 seeded players are guaranteed not to face another seeded player until the third round.

The drop in rankings could add merit to Bouchard's lawsuit that claims her earnings are continuing to take a hit as a result of the concussion.

Bouchard, who was having a miserable season, strung together three straight wins in New York and was set to face eventual Serena Williams-conqueror Roberta Vinci in the fourth round.

Bouchard played a mixed doubles match with partner Nick Kyrgios and had to go through a darkened locker room to take an ice bath. Her suit alleges the floor had a cleaning agent on it that cause her to slip, fall backward and hit her head.

Bouchard could not play against Vinci. She was forced to withdraw from the China Open some four weeks later against Andrea Petkovic after suffering dizziness in the second set.

According to tennis.com, Bouchard's lawsuit seeks "in excess of $150,000" but her attorney said the suit could seek millions of dollars.
