Yebin has a stress fracture on my 4th left lumber in her back. She should be better in abotu 2 months, but had to withdraw from SA. Read her diary http://www.yebinmok.com/ for more info!
I hope the injury is just one that rest will cure. I'm sorry not to be able to see her in SA. I'm not a big fan of the GP Championship but I like to see how skaters are going to stand up at Worlds. And Yebin could have at chance at that in US Nats.
And so the injuries begin and the first competitive program hasn't even been skated yet.
This is why it's impossible to predict the outcome of competitions. With the demanding triples and quads, it a wonder anyone is still standing at the end of the competitive season.
