Carlisle boss Greg Abbott is hoping to extend on-loan keeper Tim Krul's time at the club, but accepts his fate lies in the hands of Newcastle.
The Cumbrians are keen to keep the highly-rated youngster for another month, after being impressed by the Dutchman during his short time at the club.
His current deal is set to expire after Saturday's trip to Northampton, but his future after that point remains in the balance.
With the Magpies set to open talks with back-up shot-stopper Steve Harper this week, the outcome of those discussions will determine Krul's next move.
Should Harper decide to extend his 16-year stay at St James' Park, then Joe Kinnear will have adequate cover for regular No. 1 Shay Given.
But, if he decides to leave during the January transfer window, the Newcastle boss may decide Krul is needed back on Tyneside.
Abbott is hoping that will not be the case, with the Blues needing all the help they can get as they attempt to clamber away from the League One basement battle.
"We're chasing up the situation with Tim and I'm planning to speak to Newcastle to find out what their views are," the Carlisle coach told the News and Star.
"We want to extend it as Tim has done ever so well. Tim wants to play games and has loved it here, but it depends on what Newcastle do with their goalkeepers in the transfer window.
"He might be able to force himself into contention over there. If he comes back, there will probably be a clause in the deal so that he can be recalled at any time.
"He's a fantastic young keeper with great potential. Everybody is looking for a keeper of 6ft 3in-6ft 4in these days. He has the belief and confidence that he can be a top keeper and he certainly has the makings of that.
"If he can keep goal in League One he can keep goal in the Premiership because you're still judged on how you command the area and the decisions you make."
