Wayne Rooney will miss the rest of Manchester Unitedâ€™s festive programme after injuring knee ligaments in training.
The striker has been ruled out for between two and three weeks with the problem, which kept him out of a thrilling Boxing Day victory over Newcastle.
Rooneyâ€™s replacement Javier Hernandez scored an injury-time winner in a 4-3 success which put United seven points clear at the top of the Premier League.
And after the game Sir Alex Ferguson told MUTV the reason for Rooneyâ€™s omission from the 18-man squad.
He said, â€œIt was a volley towards the end of training. He did a ligament at the back of his knee and could be out for two to three weeks.â€
Fergusonâ€™s worst-case scenario would see the England international miss Premier League games against West Brom, Wigan and Liverpool and the FA Cup third round tie at West Ham.
