The Portugal star sustained an hip injury during the game and ‘substituted himself’, with 25 minutes left to play.
“He got real kick on the hip-joint, just like Wayne Rooney did last year when he was in pain for a while and missed a couple of games,” said United boss Sir Alex Ferguson after the game.
“There was no need for him to come to the bench, though. The best thing is to get treatment straightaway. It was the sensible thing to do.
“We will see what he is like, although I was going to make changes for the Champions League game against Aalborg on Wednesday anyway.”
