Real Madrid striker Ronaldo will be out of action for a month after undergoing an operation on his left shin in Rio.
The 29-year-old was accompanied by doctors from both his club and country after reports that Real were unhappy with the decision.
Brazilian national team doctor Jose Luiz Runco said: 'He could start to train with the ball in four weeks, more or less. We must hope that the wound heals.'
Real doctor Alfonso del Corral was quick to deny reports of a rift.
He said: 'The Brazilian Football Confederation (CBF) and Real Madrid always work together. I have never had problems with the Brazilian FA.'
