The 29-year-old hobbled off the playing field as the clock ticked down in stoppage time at the City Ground on Saturday with an injury to the lower part of his leg.
However, Royals physio Jon Fearn remains buoyant and is confident that Murray will not be sitting in the stands when the Rams visit in two weeks time.
"I would hope he'll be ok for the Derby game but we'll have to see how he responds over the next few days," said Fearn speaking to the official site.
"I'll be getting a precautionary opinion on the injury from a specialist, but it will probably just be a case of letting time heal it, and as the bleeding settles down the nerve should get better and the power return," he added.
Murray, who signed from Bristol City for £400,000 in the summer, has begun to hit form again in recent weeks and has shown some flashy touches in the past couple of matches against Ipswich and Forest. The 29-year-old capped his performance on Saturday with a beautifully crafted goal that proved to be the only strike of the game.
He has now scored five times for Reading, but his most recent goal could prove to be his most important as hopefully the Royals will be able to surge back up the table following a dismal run of seven games without a win.
