Zambia striker Clifford Mulenga has been removed from the squad and sent home from the CAF Africa Cup of Nations by coach Herve Renard for disciplinary reasons. Eric Mwenza, press officer for the Zambian Football Federation, told AFP: \"He has been excluded for disciplinary reasons\". The 24-year-old has only appeared for 20 minutes when coming off the bench in the opening 1-0 defeat of Senegal. Zambia finished top of Group A and face Group B runners-up Sudan in the last eight on Saturday.
