After his side's 5-0 rout of Doncaster in their third-round replay at Molineux, the Wolves boss later admitted to spending the day ill in bed and not getting up until 4.45pm.
"Despite my miserable demeanour, I didn't get out of my bed until 4.45pm," revealed McCarthy.
"I don't know what's wrong with me. I've been ill since the game against Chelsea (a 1-0 home win on January 5) on and off."
