I hope not, but Varvara for SURE wasn't injured so the injured players are most likely Stephens, Venus, and Serena
That's not good. I didn't see Sloane play but thought it was her typical form as of late and Venus is Venus. I saw a photo of Varvara and saw she wasn't suited up so I figured she was one. Hopefully nothing is serious and it makes sense not to play considering the US had it all won.
