Cardiff City captain Joe Ralls is leaving the club, bringing an end to 15 years at the Bluebirds.
Ralls, the Bluebirds' longest-serving player, had initially been in discussions over potentially extending his stay at Cardiff City Stadium.
But, after talks with new manager Brian Barry-Murphy, the 31-year-old midfielder will move on when his contract expires at the end of this month.
Midfielder or right-back Andy Rinomhota is also set to depart with his three-year deal also not being renewed.
A decision on their futures had been put on hold as the club awaited to appoint a successor to Omer Riza after demotion to League One, with Barry-Murphy being confirmed as new head coach last week.
Ralls thanked owner Vincent Tan and the Cardiff board on social media, and Barry-Murphy for "being completely honest with me".
"It's incredibly hard to find the words after 15 years here... but the time has come for me to move on and for the club to go in a new direction," Ralls said.
Ralls made 409 Cardiff appearances having joined the club's academy from Farnborough in 2010.
He featured in the club's first promotion to the Premier League in 2013 and was a key figure under Neil Warnock when Cardiff returned to the top flight in 2018.
Named club captain in 2022, he is among the Bluebirds' top 10 appearance makers.
Paying tribute to his impact at the south Wales club, Cardiff owned Vincent Tan said: "Players like Joe Ralls don't come around very often in the modern game. Joe has displayed incredible loyalty and love throughout his 15 years here.
"Whether it has been in the midfield, or showing leadership behind the scenes, and always joining in with our community, he has been a figurehead and a gentleman in everything he does. He has the respect of everyone at Cardiff City Football Club."
