The Colombian will now miss this year's World Cup.
Ronaldo, after victory over Granada, said: "It is bad news for the world of football. He is a friend and I am sad for him. I am sure that things will go well for him. He has been operated on by great Portuguese doctor and I am sure that he will recover sooner."
Ronaldo also spoke of Sandro Rosell's resignation at Barcelona.
"I don't have anything to say about that. I only care about what is happening at my club. Other people's clubs don't matter to me."
