That's stupid. Really, really stupid. If anything, this news is good. It shows that her back is better, and that what kept her from Wimbledon was a temporary things which she can, will and has recovered from.
At this point, I fully expect to see her at the California hardcourt events.
Well, do we know anything more about whether she did hurt her back or sustained something else apart from the concussion? NO. There's a possibility that she sustained other injuries.
So, maybe I'm not as optimistic as you are, but I hope you're right. Believe me that I really do hope Lindsay's coming back soon, but every news we get is neither a statement from Lindsay herself, nor a clear view of her actual injury. And it's been almost 4 months since she played her last match, and it's been alomst a month since she fell, but we know this only now.
She has resumed practicing in preparation for the United States Open but is not ready to give a date for a comeback.
What may mean she's not ready to play Stanford, SD, cos it's only in 2 weeks time now, or it means nothing, but it certainly doesn't meran she's 100% fit, ready to go.
