Mide Shodipo and Jack Vale have left City as part of the club’s initial January transfer window activity.
Shodipo returned to Lincolnshire on a short-term contract in October, featuring nine times and scoring once - the equalising goal against Port Vale.
That takes his total appearances for the Imps to 29 over two seasons, and he leaves following the expiry of his contract.
Vale made 17 competitive appearances for City, scoring twice, after joining on loan from Sky Bet Championship side Blackburn Rovers at the end of the summer transfer window, following long-term injuries to Ben House and Tyler Walker. He now returns to his parent club.
In addition, Morgan Worsfold-Gregg leaves the Imps to pursue further education at university in America and Julian Donnery leaves at the expiry of his two-year scholarship.
Everyone at the club thanks Mide, Jack, Morgan and Julian for their contributions and wishes them well for the rest of their careers.
