Skysports.com understands Blackpool have offered new deals to Ian Evatt, Keith Southern and Brett Ormerod.
The Seasiders have moved to offer new terms to the trio to avoid losing them for nothing at the end of the season.
All three are out of contract in the summer, but because they had options which would see their wages reduced included in their deals they have been forced to table them new contracts or risk losing them on free transfers at the end of the season.
In a similar situation as to how Everton saw Dan Gosling leave on a free to Newcastle last year, the Blackpool trio had to be offered new deals before the third Saturday in May otherwise they would be considered free agents.
Meanwhile, Blackpool are set to release goalkeeping duo Richard Kingson and Paul Rachubka at the end of the season.
Ghana international Kingson joined Blackpool on a short-term deal last September and his contract will not be renewed, while former Manchester United shot-stopper Rachubka has struggled with a series of injuries this season.
Defensive duo Danny Coid and Rob Edwards will also leave Bloomfield Road after the club decided not to take up options on their expiring contracts.
However, Ian Holloway's side have taken up the option on keeping Billy Clarke, who has missed all of the season with a ruptured cruciate knee ligament injury he sustained in pre-season.
Highly-rated young defender Ashley Eastham, who has enjoyed spells on loan at Carlisle and Cheltenham Town this season, has been offered a new deal to stay at the club.
