Mohamed Salah limped out of Egypt's 4-1 win over Swaziland on Friday evening with what appeared to be a groin injury.
Salah left the pitch in the dying minutes of the Africa Cup of Nations qualifier, heading down the tunnel after sitting on the ground for a couple of minutes.
The Liverpool forward had scored earlier in the game, catching the Swaziland keeper unaware with a corner kick snuck directly into the goal at the end of the first half. The 4-1 win keeps Egypt second in Group J, with leaders Tunisia set to play Niger on Saturday evening.
