With the Magpies not going up or down this season, John Carver's men are coasting towards the end of the season until the club appoint a long-term manager this summer.
Regardless, the Newcastle recruitment staff appear to be scouting potential signings ahead of the summer transfer window - and the Daily Mail believe that Furlong is on their radar.
Furlong, 19, is the son of former Chelsea striker Paul Furlong, and is now starting to emerge as one of QPR's brightest young prospects.
The promising right back didn't make any appearances under former QPR boss Harry Redknapp, but his replacement Chris Ramsey had no qualms about throwing the teenager in from the start in last weekend's crucial relegation battle against Hull City.
Whilst the R's lost 2-1, Furlong was solid in defence, making a strong first impression on his Premier League debut - and it appears that his performance has attracted interest.
Furlong's contract at Loftus Road expires at the end of the season, meaning he would be free to join another club, with Newcastle involved in a race for his signature alongside Premier League rivals Crystal Palace, Hull City and West Brom.
