Henly, who has caps for Scotland Under-21s, was let go by Reading after failing to make a first-team appearance in Berkshire having had loan spells at Aldershot and, during the last campaign, Welling United. He was recently turned down by Scottish club Ross County after a short trial.
The R's have just last week sold second-choice goalkeeper Alex McCarthy, another former Royal, and are currently without a back-up to former England shot-stopper Robert Green. Henly played for QPR's development squad in a friendly defeat to Hendon on Monday, officially listed by the West London outfit as a trialist, in a bid to earn a contract at Loftus Road. The 21-year-old got 90 minutes in that game, which was organised as a testimonial for the non-league side's boss Gary McCann.
Whether Henly can force his way into the QPR first-team squad - let alone a contract - remains to be seen. Not many Reading fans would have had this one down as a case of 'the one that got away' but if Chris Ramsey's side can see any potential in the youngster then that may change.
