Aston Vila have suffered more injury woes after defeat to Manchester City.
With Villa just seven points off the relegation zone, McLeish's woes are compounded by the fact centre-back Richard Dunne faces at least a month on the sidelines after seemingly dislocating his right shoulder.
With Ciaran Clark also out for a period of time after damaging knee ligaments in training on Saturday, McLeish added: "We've a specialist in looking at him (Dunne).p> "I'm not sure what is going to happen with the big 'un, whether he is going to go to hospital tonight or whatever, or what they do when a shoulder is dislocated, whether they stick it back in.
"I can't give you an answer just now, but I do believe he is going to be out for at least a month, so that's serious enough."
