Soccer:Manchester United forward Wayne Rooney will be out for "two or three weeks" after suffering a knee injury in training.

Rooney missed United’s 4-3 win over Newcastle this afternoon and Red Devils manager Alex Ferguson confirmed the striker will miss the remainder of the festive programme.

“It was a volley towards the end of training,” said Ferguson. “He did a ligament at the back of his knee and could be out for two to three weeks.”
