Here are the players out of contract at the end of the season, and the loanees who will depart the club too.
9. Joe Mason
Netted a hat-trick against Fleetwood, but has only scored two other goals in 29 appearances this term.
10. Cameron Jerome
Top-scorer this season, answering his critics who questioned his age when signing from Turkey. Was subject to Championship interest from Cardiff during the January window. Martin is eager to keep him.
11. Jay Bird
Another injury-ravaged season following a second knee surgery. Made his first team debut against Stevenage and got a brace. A deal is understood to be in the works to keep him.
12. Lasse Sorensen (loan from Stoke)
Hasn't featured much since the signings of Surman and McEachan, playing just nine times in 2021.
