Michael Kightly and Jay Bothroyd are injury doubts for Wolves' home clash with Colchester United on Wednesday.
Kightly limped off in Sunday's goalless derby draw with West Brom at The Hawthorns with an ankle strain, ending the afternoon on crutches.
Bothroyd also came off in the second-half, suffering from a dead leg.
"With the game being played Wednesday rather than Tuesday, it gives both of them an extra 24 hours," McCarthy told the Wolves website.
