Huddersfield Town have released midfielder Mickel Miller.
The 30-year-old joined the Terriers from Plymouth two years ago and made 31 league appearances for the club.
Defenders Neo Eccleston, 22, and Omari Mrisho, 20, and striker Pete Thomas, 21, have also been let go.
The League One club have taken up the one-year options on the contracts of defender Ian Togo, 19, and winger Cameron Ashia, 21.
They are in discussions with goalkeeper Nik Tzanev, 29, about extending his stay.
Huddersfield finished ninth in League One this season.
They ended the campaign under the caretaker management of Martin Drury and Jon Stead after boss Liam Manning took compassionate leave in March.
