Montenegro will face possible punishment as they were charged with racist behavior during their game against England.
UEFA has brought the charge against the nation after a section of their supporters were heard making racist comments and noises at certain England players.
PFA deputy chief executive Bobby Barnes said he spoke with UEFA president Aleksander Ceferin and confirmed action would be taken.
"Aleksander Ceferin has expressed his equal frustration with myself that racism had raised its ugly head again," Barnes said to Sky Sports.
"Aleksander reiterated his commitment to dealing with this stain on our game and to taking strong action once the evidence has been properly examined.
"I know from working with him directly on various incidents in the recent past that he has exerted his influence to ensure action has been taken over racist incidents such as this, I firmly believe he intends to tackle this issue."
