Former England goalkeeper Scott Carson has not been offered a new contract by Championship side Derby County.
Carson, 35, who has also played for Leeds United, West Brom and Liverpool, spent last season on loan with Premier League champions Manchester City.
Defender Scott Malone, 30 and winger Florian Jozefzoon, 30, have also not been offered new terms.
But the club are in talks with Andre Wisdom, Martyn Waghorn, Jack Marriott and Curtis Davies about new deals.
