Salah was taken off in stoppage time of Egypt's 4-1 win over Swaziland on Friday night, having gone down to the turf minutes earlier with what appeared to be an issue with his left leg. However, he was later forced to leave the field through injury towards the end of the game.
Although the severity of the injury is yet to be confirmed, Hany Ramzy, The Pharaohs' assistant coach, suggested his decision to withdraw from the match was more a precaution than anything that may keep him out for the long-term.
The goal put Egypt 4-0 ahead just before half-time and although there are obviously question marks over the goalkeeping, it was still a superb strike from the Liverpool forward and fans will be hoping the goal will help Salah get back to his best form when he returns to Anfield next week.
By netting the audacious effort from the corner flag, Salah set a new Egyptian record with his 13th career goal in Africa Cup of Nations qualification, going one past previous record-holder Hossam Hassan.
Liverpool have a nice spell on paper when they resume club action, with games against Huddersfield, Crvena Zvezda and Cardiff City in October.
Egypt face a return fixture against Swaziland on Tuesday in Group J.
