Hull City have allowed defender Kamil Zayatte to leave the club in order to return to France for family reasons.
Zayatte has given up a bumper contract at the KC Stadium and has left the Championship club with immediate effect.
The 25-year-old initially joined the Tigers on loan from Young Boys in 2008 before finalising a £2.5million transfer later that same season.
He scored four goals in 79 appearances with the Tigers, who will retain his registration in the event of securing future compensation if Zayatte joins another club.
"The decision has been taken on compassionate grounds and in the best interests of the player and Hull City," said head of football operations Adam Pearson.
"It's not often a player walks away from such a large contract, and we've kept his registration in case there's any compensation down the line."
A club statement added: "It is with regret that the club has come to a formal arrangement with Kamil Zayatte in order to allow the player to go home to his family in France.
"We would like to thank Kamil for his valuable contribution over the last three seasons and wish him luck for the future."
