Sunderland signing James McFadden has suffered an injury setback.

McFadden faces a spell on the sidelines after suffering a hamstring injury.

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

"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.
