Aston Villa boss Martin O'Neill admits Emile Heskey is struggling with a back injury.

The complaint ruled him out of the Bolton game.

O'Neill explained: "It's his back. It's not a serious problem to keep him out for weeks.

"I know Emile from the past and he's had an on-going back problem throughout. It comes up now and again and it gets very stiff and it obstructs him. But overall it's not a monumentally difficult injury and we're trying to get to the bottom of it."
