Youcef Atal will not be available for Algeria's remaining games at the 2019 Africa Cup of Nations in Egypt.
He will miss the semi-final clash against Nigeria at the Cairo International Stadium on Sunday.
Atal was injured in the 30th minute of the quarter-final game against Ivory Coast and further medical examinations have confirmed it to be fractured collarbone.
He was replaced by Mehdi Zeffane as the Desert Foxes advanced to the semis via a penalty shoot-out.
Atal has been one of the key players in Djamel Belmadi's side and a constant menace down the right flank with his strong runs, which posed a threat to opposition's defence.
