Former Aston Villa and Everton winger Anwar El Ghazi will have his contract terminated at Mainz for a social media post about the Israel-Gaza conflict.
El Ghazi was suspended on 17 October by the Bundesliga club, who called the now-deleted post “unacceptable”.
In a meeting on Thursday, the club wanted the 28-year-old to apologise for the perceived pro-Palestinian post.
But the Dutchman told senior executives he stands for peace and humanity for all victims of the war.
Sources told BBC Sport on Friday that El Ghazi was informed he will have his contract cancelled.
He joined the club on a free transfer on 22 September after leaving PSV Eindhoven.
Under German labour law, an employer has 14 days from the date they became aware of the gross misconduct to terminate a contract, but if they miss this deadline they would have to pay the contract out in full.
Mainz declined to comment when contacted by BBC Sport.
Nice defender Youcef Atal has been suspended and is being investigated by French prosecutors for allegedly posting an antisemitic video relating to the conflict in Israel and Gaza.
Mainz travel to face Bochum in the Bundesliga on Friday (kick-off 19:30 BST).
