31-year-old Murray has scored six goals in 15 appearances for The Royals, but with a manager change in Berkshire and uncertainty over Financial Fair Play, a return to Warnock's Palace is a possibility.
Speaking to the Croydon Advertiser, Warnock again highlighted the uncertainty over Murray's future:
"Glenn's loan ends on January 1 - I don't know all the ins and outs yet, but I've asked to have a look at him myself," said Warnock.
"The thing is, I think both clubs have agreed a fee if they decide to take him but not only have they got to come up with that fee, the player has got to agree it as well.
"I don't think it's straightforward. Put it this way, I'm in no rush for him to go. I would be playing him on Saturday at Manchester City if he was back at Palace."
Palace boss Warnock has given similar quotes before, with Royals' Director of Football Nick Hammond declaring that funds were available to make the deal permanent in January.
However, with a likely settlement based around sacking ex-manager Nigel Adkins, Reading's ability to sign the striker hangs in the balance.
