Sheffield Wednesday and Leeds have joined the hunt for Jon Otsemobor's signature, according to the Crewe defender's agent.
Dario Gradi hinted earlier in the week that Otsemobor may have already agreed to join Norwich, and Canaries boss Peter Grant later confirmed he was looking to sign the full-back.
However, agent Eric Walters says nothing has yet been finalised and insists that Otsemobor is still mulling over other options as well.
The player's contract expires in the summer and he does not plan to put pen-to-paper on a new deal at Gresty Road.
A final decision on his future will not be made before the end of the season.
"Nothing has been finalised yet," Walters told The Sentinel.
"It's true Norwich are interested, but there has also been interest from Sheffield Wednesday and Leeds United.
"We will be leaving the final decision until May, when we will speak to other clubs."
