Hmm. I don't want to sound pessimistic, but maybe it'd be Better if Vika did lose. I mean she's already I injured, and the more she's on court the worse it's going to get. Maybe a weeks break is exactly what she needs.
There's also the fact though, how bad is it? It didn't look completely unplayable, I'm sure she will want to play, this looks a good opportunity to bag another big title. Unless it's excruciating, I can't see her withdrawing.
Vika'll play and I have a feeling she'll play her best match of the tournament in this particular encounter (hopefully). I think she just probably needed to fight through her couple first matches, when the storm was stronger, and, as the tournament goes on, well, she'd feel better and better. It's certainly just the case, anyways we'll see with an eventual confirmation on court.
