The loan deals of Damon Lathrope and Chris Sharp are set to expire this week.
Torquay's Lathrope, 24, has played five times for the Bulls in the Conference, ending up on the losing side just once, and also came on as a sub in the FA Trophy game. Given the financial situation at Edgar Street an extension of the loan appears unlikely.
Sharp, 27, has played only three times for Lincoln during his month but is expected to make a fourth appearance as the Imps take on Gateshead tonight. It is widely expected in Lincolnshire that his loan will be extended with boss Gary Simpson having missed out on another striker target before the loan window closed last week.
