Egypt's FA on Wednesday said it had met with Salah's doctor in Spain, and that the player's injury would not keep him out any longer than three weeks.
Egypt will open their third ever World Cup campaign, and their first in 28 years, with a game against Uruguay, before meeting hosts Russian Federation four days later.
But if he misses those games, he could play in Egypt's final group match against Saudi Arabia on June 25.
Egyptians were exceptionally angry at the incident given it's potential ramifications for their World Cup campaign in just a few weeks time.
Salah has travelled to Valencia, in Spain for treatment where he will be assessed by the Egyptian national team doctor also.
That would have ruled him out of Egypt's first appearance in the World Cup since 1990.
Liverpool coach Juergen Klopp said "anything is possible" but that Salah is doubtful for the World Cup.
Heart-broken Loris Karius has apologised to Liverpool's shattered stars after his costly mistakes condemned the Reds to defeat in the Champions League against Real Madrid.
"Obviously I need to be playing week in, week out and that hasn't happened this season", the 28-year-old said.
Pons explained that the injury is likely to sideline Salah for "three to four weeks" but that the hope is to reduce that timeframe.
Egypt's opening game against Uruguay is in 16 days, on June 15.
Egypt fans will now be breathing a sigh of relief as Salah was their stand-out player during the qualification stages, and enjoyed a record-breaking debut season with Liverpool.
