Estonian TV and Radio website said Zopp is going to play qualies here after 7 month injury break.(stress fracture of vertebra)
I dont know if he is using protected ranking in Nice or not, perhaps he is saving it on bigger tournaments. News said : after Nice Zopp will decide if he is going to play RG main draw (with protected ranking) or not.His back is still not 100 % healthy, but lot better now, at least he can practice.
I think financially it makes sense to play RG, since you cant use PR very long time anyway and even slam 1st round pays lot of money.
