She Kicks interviews says she was out for a few weeks
Arsenal cannot afford to fill up a bench with 5 valid subs...
"TL: Your return should have been followed by immediately stepping into action, first in the FA Cup and three days later in the Champions League. But an injury put paid to that mouth-watering prospect – how big a blow was that?
KS: It was a massive disappointment and so frustrating – I was on a high when the signing went through, but then on the same day the club doctor sent me for precautionary X-rays on my leg and the damage was worse than I thought. I got hit by a late challenge in the game against France at the Cyprus Cup and it was certainly painful, but it was thought that it might only be bruising on the bone. It was a bit more than that though, the bone is chipped just above the ankle, and it looks like I could be out for two to three weeks."http://www.shekicks.net/flog/blogs/post/526
