James McFadden has injured his hamstring during training, Martin O'Neill has revealed.

The 29-year-old is yet to make his debut for Sunderland, having joined the Black Cats after being released by Everton in the summer.

Sunderland boss O'Neill told The Sun: "I don't know if we will see James in the team any time soon because on Thursday he pulled up with a hamstring.

"I hope it is not too serious, but he was certainly feeling it. So that is a setback. It is a real shame because James has worked exceptionally hard on his fitness and was enjoying the training.

"He needs to have a chance and I hope the hamstring is not too serious. You have to remember he did not play often for Everton last season."

McFadden's contract at Sunderland runs out in January.
