Ognjenoviç wasn't in the Serbian roster What happened to her? Also having Mihajloviç and Nikoliç at the same time on court is not a smart idea against better teams
According to this, she has "health problems."

I fully expect Zivkovic will be good enough to make sure they qualify, but if she were to get injured somehow, I wonder what Terzic would do without another setter.
