Derby County manager Nigel Clough has seen four members of his first-team squad sign new 12-month contracts at Pride Park.
Striker Conor Doyle has been handed a contract extension, despite only making three appearances last season.
Goalkeepers Saul Deeney and Ross Atkins have also committed their immediate future to the Rams, but Atkins is expected to go out on loan at the beginning of the season.
Full-back Michael Hoganson will remain a part of Derby's Under-21 squad over the next year.
