However, he has declared himself "fit and ready to play" to team-mates and is eager to figure as soon as possible - even believing he could return ahead of his newly-scheduled comeback at Everton on September 15.
Indeed, manager Sir Alex Ferguson revealed the striker's desire to return last weekend.
Ferguson said: "Rooney's fine. He's jogging and he even wanted to play against Spurs! Typical Rooney, he wanted to play with an injection. It's quite possible he'll be back in three weeks."
