Aston Villa boss Martin O'Neill has admitted he has concerns over a trio of key players ahead of Sunday's pivotal Midlands derby clash with Birmingham City.
The Villans landed a 2-0 win at struggling Hull City in midweek but the success looks to have came at a cost.
Defender Richard Dunne suffered a cut to his head following an ugly aerial challenge with Jan Vennegoor of Hesselink that required stitches, while Stephen Warnock battled through the 90 minutes with an ankle problem.
To make matters worse, influential midfielder Stiliyan Petrov was forced out of the action with a groin complaint at the death and it could leave O'Neill with a number of problems for the fierce weekend showdown.
Speaking to reporters, O'Neill said: "I think Richard's cut may have reopened but I'm hoping he is going to be okay.
"Stephen was kicked twice in the same spot within a matter of moments but he carried on to the end.
"Stiliyan had a kick in the groin which was very sore at half-time, but he stayed on until close to the end. We'll see how they are."
