BBC West Midlands correspondent Mark Regan has claimed McCormack is on the brink of a Fulham return.
Speaking on local radio, he said the 30-year-old's transfer would be announced "very shorty" by Villa.
McCormack was omitted from the matchday squad last Saturday in the 2-2 draw with Preston at Villa Park.
He tweeted that before the game yesterday and Bruce denied there was anything happening on that front after the game.
