Northern Ireland's Kyle Lafferty has been withdrawn from the squad for their Nations League fixtures with Kosovo and Greece.
A video emerged that appeared to show the Enniskillen man using sectarian language.
The clip shows the striker posing for a photograph with a supporter. He is then seen responding to a comment of "Up the Celts" from the same man.
Explicit language warning*
