Robinho was stretchered off while on international duty for Brazil in the clash with Colombia on Wednesday.
“We are still waiting for real definite news,” Hughes told Sky Sports News.
“But we have yet to hear from their medical department so we take the view that he is fit and well.
“We have looked at the tape and seen the incident when he had to come off.
“From looking at those pictures it doesn’t look a significant injury, so we expect him to be fit when he returns.”
