As Eugenie Bouchard returns to the scene of her concussion, she fires back at USTA on Twitter

NEW YORK – Genie Bouchard admitted to having a few flashbacks to last September when she set foot on the US Open site earlier this week.

But she's thinking positive, and she's leaving the pending lawsuit against the USTA filed in the wake of the concussion she suffered in the women's locker room last Sept. 4 with her lawyers.

The comment from the USTA late last week about the 22-year-old's focus being on matters other than tennis did not go unnoticed.

And as she sat in her hotel room Sunday night watching the Video Music Awards (well, practicaly live-Tweeting the VMAs), she did get a shot in.

Zzzzing ....

Bouchard probably could have attended the awards on Sunday night, since she is not scheduled to play her first-round match until Tuesday. But she hung out in her hotel room.

Earlier in the day, Bouchard practiced for an hour and a half with Andrea Petkovic of Germany. Not unironically given the circumstances, Petkovic was Bouchard's opponent for the only match she attempted to play in 2015 after being on the shelf when she recovered from the concussion and later, suffered more symptoms during an earlier comeback attempt on the fall Asian swing.

She had to retire during that match against Petkovic in Beijing, and didn't play for the rest of the 2015 season.

Here's what it looked like. The raised arms at the end came after Petkovic, who was serving, announced that the next point was going to be match point – and Bouchard won it.

It's also worth noting that Bouchard's first-round match against Katerina Siniakova has been scheduled on Tuesday, and the match, between the No. 40 and No. 73 players in the world, neither seeded, has been put on the brand-new Grandstand court,  the third-largest court on site after Arthur Ashe and Louis Armstrong stadiums.
