West Brom have confirmed that James Morrison, Gareth Barry and Boaz Myhill will not be offered new contracts following the club's play-off defeat.
The Baggies failed to make an immediate return to the Premier League following last season's relegation when they were beaten by Aston Villa earlier this week.
Albion are still searching for a new head coach after parting company with Darren Moore in March – Jimmy Shan working in a caretaker capacity for the last two months.
Technical director Luke Dowling said of the released trio: "They've been great pros. They're at an age and stage in their careers where we have to offer them contracts by the third Saturday in May, it's the rules and regulations. We have to do that with any out-of-contract player.
"But the door won't be completely shut to them because we'll wait for me to have a conversation with the new head coach to see if he would like them to be part of his plans next season. If he does then negotiations will start if they haven't signed for another club."
Wes Hoolahan and Tyrone Mears have also been released after their season-long contracts came to an end.
Dowling added: "On behalf of everyone at Albion I'd also like to thank Wes and Tyrone who, when they came in and played, were great.
“Walking away from the ground on Tuesday evening [after losing on aggregate to Villa] I thought from start to finish it was a night to be proud to work for West Bromwich Albion.
"I've only been here since September but I'm not sure it's been the happiest of places over the past few seasons. But that's something we need to change. We will do our upmost behind the scenes to change that."
Meanwhile, Aston Villa and Derby County will meet in the Championship play-off final on Monday 27th May. The Villans are 8/13 to secure promotion, with the Rams available at 13/10.
