Following their elimination from the Championship play-offs on Monday evening, Derby have announced that Darren Bent, Jason Shackell and Chris Baird will all be leaving the club this summer.
Bent joined the Rams from Aston Villa in 2015 and scored 12 goals in 53 appearances during his three year spell with the Championship club.
The 34-year-old spent the latter part of last season on loan at local rivals Burton, where he was unable to prevent the Brewers from slipping into League One.
Shackell has also been with Derby since 2015 after he began a second stint with the club following a move from Burnley.
The center-back also spent much of last season out on loan, where he helped Millwall in their unsuccessful push for a play-off position.
Meanwhile, Baird has made over 50 appearances for the Rams and clocked up 79 caps for the Northern Ireland national side before announcing his retirement from international football in 2016.
Derby's season ended after their 2-0 defeat at Fulham on Monday evening, which saw the Cottagers progress into next weekend's play-off final where they will come up against Aston Villa.
