Seydou Doumbia walked out on the Ivory Coast squad during the international break.
Newcastle United's on-loan striker reportedly rowed with coach Michel Dussuyer.
And Doumbia did not travel to Sudan with his international team-mates for Tuesday's African Cup of Nations qualifier, which ended 1-1.
The 28-year-old, on a half-season loan from AS Roma, had been an unused substitute in the Ivory Coast's 1-0 home win over Sudan in Abidjan last Friday.
Doumbia has made three substitute appearances for Newcastle.
