There is a prediction going that Shekar Kammula next movie would be with Nagarjuna. Some time ago a story was made for Nag by Shekar. Having seen the success of Shekar, now Nagarjuna may not be interested to leave Shekar without doing his job. If this really works out then most likely Nagarjuna would be playing role of a Doctor according to the sources. We need to wait and watch until its really put on board.
