Yahoo Sports reports: Former Liverpool standout and Egypt forward Mohamed Salah left Friday night's 1-1 draw with Iran at the World Cup because of a left knee injury, coach Hossam Hassan said. In the 57th minute, Salah was surprisingly replaced by Mostafa Zico. In comments translated from Arabic, Hassan said Salah is being assessed by the team's medical staff, and will have another examination when Egypt returns to the team hotel.
