Algeria goalkeeper out of Nations Cup
Gaouaoui, one of the heroes of his country's surprise qualification for the 2010 World Cup finals, is being sent home for treatment.
Algeria will be allowed to replace Gaouaoui on medical grounds because they have yet to play their opening match at the tournament in Angola, according to Nations Cup regulations.
Algerian officials said 31-year-old Nassim Ousserir would be flown in as a replacement. Ousserir has played only once for Algeria in the past six years.
Algeria face Malawi in Luanda in their first Group A match of the tournament which starts on Sunday.
