Egypt have agreed to release Liverpool striker Mohamed Salah from coach Javier Aguirre's squad.
Salah was withdrawn late on in the 4-1 victory over Swaziland , having earlier scored direct from a corner.
Egypt play a return fixture against the same opponents on Tuesday but the Egyptian FA have confirmed Salah will play no part.
A statement from the Egyptian Football Association read: "Javier Aguirre has decided to let Mohamed Salah return to his club and not participate in the Swaziland match on Tuesday to give him more rest.
"During the previous match against Swaziland, Salah complained of stress in the musculoskeletal muscle.
"He was examined medically and radiation was performed on the area of complaint after the game."
