Manchester United have received an injury boost with the news that Park Ji-sung, Mikael Silvestre and Ben Foster are all making good progress.
Silvestre sustained a similar problem in September and, while he was initially expected to miss the whole season, is now on course for a return early next year.
Foster, meanwhile, is also out with a knee problem and, having undergone surgery in the summer, could be back as early as Ferbruary.
"Ji is back training and he will almost definitely be playing by the end of December," Sir Alex Ferguson told the club's official website.
"He is doing really well. He may have to wait until the beginning of next year, but he is certainly on the way back. He's doing good training.
"Mikael Silvestre, as we predicted, could be back in March, and Ben Foster is also doing some good work. We expect him to be available in February or maybe March."
