It looks like it wasn't only due to injury
Look what Terzic said:
"It's always the most difficult part of our job, especially when players like Tijana Malesevic have to be cut off. She deserved to go to London, both as a player and as a person, but unfortunately, the situation was such that we had to take some other things in consideration when we made the final roster."
The latest news is that Maja is having some problems with a hand injury and is not training at the moment.
Hope that's not serious
