The Canaries are looking to bolster their attacking options during the January transfer window, and have lodged bids for Swansea forward Danny Graham as well as Celtic striker Gary Hooper, with an improved offer on what is understood to have been an initial £5million deal knocked back by the Scottish club.
Leeds frontman Luciano Becchio, who has handed in a transfer request, and QPR forward Jamie Mackie are others said to be on Hughton's radar. " Kei Kamara is a player we have made enquiries about, but any progress remains behind closed doors," Hughton said at a press conference.
Sierra Leone international Kamara had a trial with Stoke in December, but was not offered a deal, and Norwich could now be ready to offer the 28-year-old a chance to play in the English top flight should a deal be struck with the Major League Soccer side.
On Wednesday Norwich announced goalkeeper Lee Camp was set to sign following his release from Nottingham Forest. The 28-year-old Northern Ireland international will provide experienced cover as John Ruddy continues his recovery from a thigh injury.
Hughton is determined to keep a lid on any transfer developments over the closing days of the January window, but accepts the club are sometimes swimming against the tide of continued speculation.
"Generally 99 per cent of what is in the media has no fact. Any progress or not will take place behind-the-scenes," the Canaries manager said. "If and when there is any definite news, we will get it to you."
Hughton, though, would not discuss the matter further when pressed by reporters, saying: "This is something that got into the public domain and sometimes it is difficult to stop. We are where we are on that one.
"People now know what the facts are. Yes, there was a bid put in. The rest we will have to wait and see. What I can control is what I tell you now. Anything we try to do is done very much club-to-club and we try to do as much as possible in the appropriate way."
