Defender Paul Robson has left Lincoln City along with three other players.
The full-back was the latest player to go from Sincil Bank in a day which also saw the departure of goalkeeper Jake Turner and young defenders Elliot Green and Dan Coupland.
Robson played 12 times for City this season at both right and left back.
Meanwhile, former Scunthorpe United trainee Turner had found his chances limited following the arrival of David Preece as back up for number one Paul Farman.
Turner had been on loan at Evo-Stik League Premier Division side Grantham Town earlier in the month.
