Wes Morgan, who is among those set to be out of contract in the summer, fears Leicester City are playing a risky game.
The Foxes fended off advances from Morgan's former employers Nottingham Forest over the summer, with the centre-half considered to be crucial to their plans.
They have, however, failed to sit down and thrash out an extension to his current deal.
That has left them open to further offers in January or the threat of losing their skipper for nothing at the end of the season.
Morgan is not the only one sweating on his future and hopes the Leicester board will soon look to address the issue of who will and who will not be staying at the King Power Stadium.
He said: "It is unfortunate nothing has been sorted. Nothing has been said either.
"There are a lot of boys up at the end of the season and they are thinking about the situation.
"It would be nice to see support from upstairs. Hopefully, they will look at what our boys have done and reward some of them, or tell us one way or the other.
"We have a great team and it would be unfortunate if some of the players did go or start thinking about elsewhere."
