Oh no, poor Nastya. I hope she doesn´t have a really bad injury because I´m looking forward to her taking this year´s Roland Garros title! Get better soon, girl...you need all your power for your next match.
Ok, the commentator just said what Anastasia´s problem was: She hurt her neck during a point (kinda rotated it), the medical woman had to get it back into position...this must had hurt. Everything´s fine now.
