There was an AP story that stated she is working with her trainer "in hopes" of being ready to start the US Open. Hopefully another month (give or take) of training and not overdoing the foot, will yield her the ability to play the Open despite the injury.
Of course, if she does play the Open, she'll be seeded at best #26 - and most likely a few notches lower. That means a big gun in the 3rd Round....
I'm just trying to be optimistic that she'll play. Win or lose, she's still my favorite.
