Lincoln have made defender Adam Watts, winger Gavin McCallum and midfielder Ali Fuseini available for loan.
Boss David Holdsworth wants to reshape his squad and has said he would have to let some of his current squad leave to free up funds for new players.
The trio, whose contracts run to the end of the season, are among the highest wage-earners at the Blue Square Bet Premier club.
All were part of the Imps squad which was relegated from the Football League.
They were transfer-listed during the summer without success - McCallum, 24, and Fuseini, 22, for a fee and Watts, 23, on a free transfer.
