Norwich target Hooper had already been the subject of three failed bids from the Barclays Premier League side, with reports of fourth and fifth offers being tabled by the Canaries.
However, Celtic made it clear they had no intention of sanctioning the departure of one of their key players, especially with a Champions League last-16 clash against Juventus to look forward to.
Boss Neil Lennon took to his official Twitter account to clarify the situation a couple of hours before the deadline.
He tweeted: "Contrary to reports there have been no fresh bids for Gary and even if there are they will be rejected..he is NOT for sale."
Lennon will no doubt be thrilled that Hooper will remain in the east end of Glasgow for now.
But attempts at bolstering his strike force appear to have been scuppered after Wolves manager Dean Saunders told a press conference, after their match against Leicester, that interest in Doyle from Celtic had been rebuffed.
Meanwhile, Trelleborgs goalkeeper Viktor Noring was pictured arriving at Celtic Park but there has been no confirmation as yet from the Hoops on whether a deal has been done.
