Blackpool are bidding to keep all five of their loan players at Bloomfield Road.
Will Aimson, Elliot Lee, Andy Little, Dean Lyness and Hayden White are all due to return to their parent clubs following Saturday’s game at Burton Albion.
It would leave a huge hole in Neil McDonald’s squad, who have shown improvement in recent weeks and recorded three straight wins before Monday’s setback at Barnsley.
And the Pool boss says he wants the matter resolving as quickly as possible.
“It’s a huge concern,” admitted McDonald. “But we are trying to do something with all of those five players. Hopefully we can get them done.
“If we need to use the extensions on the loans we’ll do that, but we are also in talks about permanent deals.”
Pool are hoping to extend loan deals for West Ham’s Lee and Hull’s Aimson until the end of the season but are waiting on answers from both.
A new deal for keeper Lyness is less urgent, with first-choice Colin Doyle back in training.
The Burton keeper could well have played his last game for Pool as he won’t be allowed to play against his parent club this weekend. When asked about his goalkeeping situation, McDonald seemed determined to keep details close to his chest.
He said: “We will see who keeps goal. We’ll see if Colin Doyle is available.
“For once I’m going to keep my details about injuries and transfers a secret. I don’t want to talk about it.”
Should Doyle fail to return to action this weekend, Kyle Letheren will play between the sticks for Pool for the first time since last month’s Johnstone’s Paint Trophy defeat at Wigan.
Pool have enquired about signing Preston striker Little on a permanent deal, although concerns about his long-term fitness remain. He has come off the bench in Pool’s last two games, having been injured on his debut at Southend last month.
As for full-back White, the Seasiders’ could be helped in their attempts to sign him by the financial mess at his parent club Bolton.
The Trotters, who are £179.2m in debt, have received a winding-up petition over unpaid taxes and a transfer ban.
Problems paying player wages could result in many of the squad being allowed to leave on free transfers.
Should the club not meet today’s deadline to pay wages in full, then the whole squad, including White, could leave on 12-days’ notice.
