"Junior is a very good player and somebody I have worked with before," Hughes told The Sentinel.
"He's obviously started the season off well, but I'm not sure if he's available. If we are able to bring in players of that quality, we will try and do that. But we have got to be patient.
"Ideally, you want your targets in through the door a couple of weeks before the season starts, but that hasn't been possible for whatever reason and there is enough time to get players in."
QPR counterpart Harry Redknapp says it will take a substantial offer to prise the Canadian away.
"If Mark wants him, he or someone else has to make a big offer," he explained to the Fulham Chronicle.
