Sky Sports understands Akpo Sodje's contract talks with Preston have stalled.
Sodje's short-term deal at Deepdale runs out after this weekend's game with Crawley.
The 32-year-old originally signed a one-month contract when he arrived in August after impressing in pre-season for Graham Westley's side.
The former Charlton and Sheffield Wednesday man has been a revelation since his arrival at Deepdale, netting four goals in six games this season.
Sodje was promised a longer-term deal if he proved himself during his initial four week stint, but Preston have only offered the player another monthly contract.
The player's agent, Jonathan Hope, admitted Sodje was disappointed with the club's offer and that a number of clubs are keeping tabs on his situation.
"I'm really disappointed in the second month contract offer from Preston Nortn End," Hope told skysports.com.
"Akpo Sodje and myself had a good agreement on a one month contract to prove himself and that would lead to a year's contract.
"Akpo, in my opinion, has exceeded this expectation and has battled hard for a full contract whilst dismissing interest from Russia, Belgium, Norway and Malta.
"Sadly, as it stands, we are no further forward to extending his deal at Preston. Akpo wants to be a Preston player but not on a month-to-month basis.
"We honoured our end and he produced. I have been inundated with offers throughout the UK but all looking towards January realistically.
"We will take up further talks tomorrow and after three weeks trial to gain a one month deal leading to a year this is a disappointing after what Akpo has produced.
"Hopefully the future of Sodje will be clear soon."
