Sir Alex Ferguson has confirmed that Nemanja Vidic will not be involved in Manchester United's Champions League encounter with Cluj at Old Trafford on Wednesday.
However, Wednesday's game will come too early in his recovery and he will not be considered for Sunday's Manchester derby either.
"I do not think he will play," said Ferguson. "He feels he needs another few days' training. He will not play in the derby if he doesn't play (on Wednesday), although I wasn't considering him for Sunday anyway."
"He's showing good promise now. It is much better and I don't think he is far away," said Ferguson.
Meanwhile, Ferguson confirmed that while he will make changes to his line-up on Wednesday, Wayne Rooney will be in his starting XI.
"It has always been the case that Wayne needs to be playing games to get his match fitness," said Ferguson.
"He is a really strongly built lad. If he misses a game he needs three to come back."
Man United squad v Cluj: Lindegaard, De Gea, Rafael, Jones, Smalling, Wootton, Ferdinand, Buttner, Evra, Cleverley, Giggs, Fletcher, Powell, Scholes, Carrick, Young, Hernandez, Welbeck, Rooney, Van Persie.
