The midfielder has had an excellent season with non-league Ilkeston Town.
QPR are set to launch an assault on Premier League promotion once again this upcoming season and have begun to bring in players to do the job.
They have already snapped up the likes of Jay Emmanuel-Thomas, Ben Gladwin, Massimo Luongo, Jamie Mackie and Joseph N’Guessan and now have a talented youngster on trial, whose second name should sound familiar to Nottingham Forest fans.
Callum is of course the son of Forest legend Steve Chettle.
The Nottingham-born centre-back was at Forest from 1983 to 1999, playing over 500 times for the club and guiding them to a best ever Premier League finish back in 1995.
After he left Forest he ended up at Barnsley, Grimsby Town and Burton Albion before hanging up his boots whilst at Ilkeston Town ten years ago.
Chettle Jr has been in terrific form for the Northern Premier Division side Ilkeston last season, so much so he was recently called up to the England 'C' team - the only member of the squad playing outside the Conference system.
Now the youngster, who was released by Forest aged 15, has a chance to earn a contract in The Championship for next season.
