Blackpool have released former captain James Husband after seven years with the club.
The 32-year-old initially joined the Tangerines on loan from Norwich in July 2019 and made a total of 209 league appearances.
He was stripped of the club’s captaincy by boss Ian Evatt in February after being sent off in the 4-0 home defeat by Plymouth but won his place back in the team for the final eight games.
The League One side are in discussions with goalkeeper Bailey Peacock-Farrell, 29, and striker Ashley Fletcher, 30, about new contracts.
Meanwhile, the club have exercised the options on the deals of Olly Casey, Ryan Finnigan, CJ Hamilton, Kylian Kouassi, Andy Lyons and Albie Morgan.
Blackpool finished 13th this season after winning their final four league games.
