Carlton has rejoined the Shrimps on a short-term deal after impressing in training following his release by Bury.
McIlroy said: "Danny has done well in training and we know what he is capable of.
"He can offer us something different and we are all pleased to be working with him again."
McIlroy made two changes to his side for the 3-3 draw at Northampton in midweek, with Laurence Wilson and Andy Holdsworth returning to the side at the expense of Garry Hunter and Scott Brown.
Winger Chris Shuker will be assessed after missing the last two games with a hamstring injury but defender Paul Scott will definitely remain absent as he recovers from a knee operation.
