Mohamed Salah scored directly from a corner before being forced off with a muscle injury in the closing stages of Egypt's 4-1 win over Swaziland on Friday night.
Salah has struggled for goals at Liverpool this season having won the Golden Boot with 32 Premier League goals in the 2017/18 campaign, and has failed to find the target in his last four games for Jurgen Klopp's side.
Liverpool fans may take heart from the fact he at least found the net in the Africa Cup of Nations Group J qualifying match at the Al-Salam Stadium in Cairo, albeit in a match against a side ranked 136th in the world by FIFA.
Taking an inswinging corner from the right-hand side, Salah produced an audacious effort which caught out the Swaziland goalkeeper and nestled in the goal.
But there were concerning signs for Liverpool with Salah in heavy strapping at the end of the match, the forward briefly returning to action after treatment before being substituted a minute into stoppage time.
Egypt are next in action on Tuesday in the return match at the Mavuso Sports Centre in Manzini and Pharaohs' assistant manager Hany Ramzy was hopeful Salah's injury was not too serious.
"[The] initial diagnosis of the medical staff of [the] Egypt national team is that Salah suffered a muscular injury," Ramzy told BeIN Sports.
"He will be examined to determine the details, but in my opinion it is not serious."
Liverpool's next game is away to Huddersfield on October 20 when the Premier League resumes after the international break.
