The departure of the former World Cup striker was announced after a meeting of the Senegal Football Federation in Dakar on Tuesday.
After a dominant display in qualifying, Senegal went into the Nations Cup in Equatorial Guinea and Gabon as one of the favourites.
However, they suffered arguably the biggest shock in the history of the tournament when they lost to Equatorial Guinea, ranked some 100 places below them.
