Gareth McAuley fears former teammate Kyle Lafferty's international career could be over.
Lafferty was withdrawn from Northern Ireland's squad on the eve of the Nations League game with Kosovo after a video circulated online appearing to show the Kilmarnock striker using sectarian language.
His club Kilmarnock has launched its own investigation into the matter, while Northern Ireland boss Ian Baraclough has refused to rule out a return for the 35-year-old striker.
