Sky Sports understands a number of clubs are tracking highly-rated Carlisle United midfielder Brad Potts.
Sheffield United are planning to send Andy Butler back out on loan after seeing an agreement with Walsall collapse.
Hughes has yet to see his side win in the Premier League this season and Rangers sit bottom of the table despite an influx of big-name signings over the course of the summer.
Despite their meagre tally of only two points, QPR's chairman Tony Fernandes has backed Hughes and Hill has revealed the players also believe the Welshman will turn things around.
"Everybody on the inside is pulling in the same direction and trying to get the result we need," he told the Fulham Chronicle.
"The gaffer's confident he can turn things around - he wouldn't be here if he wasn't. He's still got the full support of all the boys. We're fully behind him and the staff."
The 33-year-old defender likened Hughes' situation to that of Tottenham boss Andre Villas-Boas.
The Spurs manager was under intense early pressure after taking over at White Hart Lane in July and starting the season slowly.
But following a string of good results, including a 3-2 victory over Manchester United at Old Trafford, Villas-Boas is now much more comfortable and Hill feels the same could be said of Hughes in a month's time.
"If you have three or four bad results, people from outside the club start writing things and pointing fingers," he said.
"If you look at the Tottenham manager three or four weeks ago, everyone was saying he was a bad manager. All of a sudden he gets a few results and nothing is said."
