John Coleman knows other club's decisions will affect his squad as he starts his January planning.
The Reds boss has seven loan players in his squad – four with deals up at the beginning of next month and three who could be recalled by their parent club.
Striker Connor Hall (Bolton), midfielder Dan Barlaser (Newcastle) and defenders Michael Iheikwe (Rotherham) and Nick Anderton (Blackpool) all have contracts until the start of January.
Goalkeeper Connor Ripley (Middlesbrough), forward Luke Charman (Newcastle) and defender Matty Platt (Blackburn) have deals until the end of the season but there is the possibility of a recall in January in their contracts.
“It's up in the air as we are waiting to hear from their parent clubs,” said Coleman. “We are trying to keep them all but I don't think we will be successful. We are also looking at other options.
“Matty Platt and Luke Charman have been victims of circumstance as you can only have five loan players in a matchday squad and they have been unlucky with game-time.
“Connor Hall made his first start against Shrewsbury and he acquitted himself well, made some intelligent runs and his link up play was good.
"We are just waiting really."
Coleman also praised striker Billy Kee as he got back on the scoresheet against Shrewsbury to take his tally to eight goals for the season.
“I was delighted for Billy. I think the last three games he has been sensational and he got his rewards for the effort he has put in against Shrewsbury.
“He has been working hard in the last few weeks to get fitter, stronger and more focused and he is reaping the benefits.”
