The former Manchester United man damaged a knee during Sunday's 1-1 FA Cup fourth round draw with Middlesbrough, and it was at first feared that his season could be over.

However, a scan has revealed that the damage may not be as extensive as was first thought.

Manager Martin O'Neill said: "We don't think he needs the operation, but he will be two weeks in a brace, two weeks elsewhere and you are looking at probably about eight weeks before he is back.

"But at one stage, it looked like a season-ending injury."

Midfielder David Vaughan too, could be missing for several weeks after damaging ankle ligaments during the same game.

O'Neill said: "David was feeling better today, but he is still very, very sore and the swelling is still up, and we are looking at a few weeks for him."

However, the news is better of midfielder Lee Cattermole, who missed the reunion with his former club after suffering a hamstring strain in training.

O'Neill said: "Lee is feeling a lot better and he is hoping to start running at the back end of next week."
