There is also concern over striker Assane Diao, who suffered an injury playing for Como against AS Roma in Serie A on Monday.
Como coach Cesc Fabregas said he had asked Senegal not to select the 20-year-old for the tournament in Morocco, where they are in Group D with Benin, Botswana and the Democratic Republic of Congo.
Senegal’s first game is against Botswana in Tangier next Tuesday.
