But The News understands there’s no interest in the Northern Ireland international who’s made 212 appearances for the Londoners.
The Blues were said to preparing a last-ditch move for the 29-year-old, according to reports.
Pompey are at the limit of the £2.5m wage cap they are operating to, however, and would not be able to accommodate a player of Ferguson’s earning power.
Kenny Jackett is also well stocked down the left flank where he has Ronan Curtis and Michael Jacobs as attacking options and Lee Brown vying with new boy Charlie Daniels to start at left-back.
Pompey also have their full complement of 22 senior players, which is the number of players they can name under the squad restrictions voted in at League One and League Two last summer.
