However it says she'll be out until the end of the season, recovery as usual with this injury will take 6-9 months. If everything goes perfectly she might be ready for OG, but then it will be questionable in what kind of shape...
This is a big blow for Uralochka and also for NT
Isn't this the same injury that Nagaoka has? She is becoming my favorite Rus player and I don't want her career taking the same turns as Nagaoka's (another of my fav)
