Egypt captain Mohamed Salah went off with an injury late in the first half of his team's Africa Cup of Nations game against Ghana on Thursday.
Salah fell to the ground with an apparent hamstring problem, handing over the armband to defender Ahmed Hegazi as he was replaced by Mostafa Fathi.
Mohammed Kudus scored the opening goal moments later as Ghana took a 1-0 lead into halftime of the Group B match.
Liverpool forward Salah struck a stoppage-time equaliser from the spot in Egypt's first game in Ivory Coast as the record seven-time champions drew 2-2 with Mozambique.
